Understanding Foreign Aid vs. Military Assistance

Last updated 3 days ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

The United States engages with the world through various means, and two of the most significant are foreign aid and military assistance.

Both serve as instruments of U.S. foreign policy, involve substantial financial commitments, and aim to serve American interests.

However, they differ fundamentally in their primary objectives, the types of support provided, and the U.S. government agencies responsible for their management.

What is U.S. Foreign Aid?

Foreign aid encompasses the transfer of resources—money, goods, or services—from the U.S. government to other countries or international organizations. These resources support a wide array of objectives, from humanitarian relief in times of crisis to long-term development aimed at fostering economic growth, improving health and education, and promoting democratic governance.

The U.S. government defines foreign assistance as a key instrument of its foreign policy. This assistance can manifest in numerous forms, including grants for projects implemented by non-profit organizations, businesses, U.S. government agencies, foreign governments, and multilateral organizations.

The scope of these projects is vast, covering everything from tangible assets like vaccines, food, and infrastructure to intangible support such as technical advice, training, and research. In some instances, aid is provided as direct budget support to foreign governments or multilateral organizations.

The Budget Reality

Americans dramatically overestimate how much the country spends on foreign aid. Opinion polls show that many believe it accounts for about 25% of the federal budget. The reality is different: foreign aid typically constitutes only about 1% of the U.S. federal budget.

In Fiscal Year 2023, foreign aid disbursements represented 1.3% of federal spending. This significant overestimation may stem from a general misunderstanding of what foreign aid entails. Interestingly, while polls might suggest a desire to cut foreign aid, support often increases when specific programs and their goals are detailed.

The U.S. government utilizes the Standardized Program Structure and Definitions (SPSD) to categorize foreign assistance, providing a common language for describing and comparing programs. This system is crucial for transparency and effective management.

One critical aspect is the distinction between “obligations” and “disbursements.” Obligations are legally binding pledges by the government to pay for promised goods or services, while disbursements represent the actual transfer of money. For FY 2023, the U.S. committed approximately $79.5 billion in foreign aid.

Goals of U.S. Foreign Aid

The United States employs foreign aid as a multifaceted foreign policy tool to achieve several interconnected goals. These objectives advance U.S. interests abroad while simultaneously promoting democracy, improving humanitarian conditions, and fostering global economic development.

Many policymakers view foreign aid as an instrument of “soft power,” a means to advance U.S. interests and build positive relationships without resorting to more coercive measures. The underlying premise is that countries benefiting from U.S. aid are more likely to view the U.S. favorably and cooperate on shared objectives.

The Congressional Research Service outlines three broad, often overlapping, rationales cited in support of foreign aid:

National Security: Aid can contribute to building stability and countering international threats by promoting global prosperity, public health, environmental protection, democracy, the rule of law, and the military readiness of partners and allies.

Commercial Interests: Supporting economic growth and trade integration in other countries can expand markets for U.S. exports, thereby fostering American economic opportunities and jobs. The Marshall Plan following World War II serves as a historical example, being both an act of generosity to rebuild Europe and a means to finance European purchases of U.S. goods, which also served to counter Soviet influence.

U.S. Values and Goodwill: Meeting basic human needs—such as food, shelter, and medicine—for vulnerable populations and combating global poverty reflects core U.S. values and can enhance America’s global leadership and goodwill.

Strategic Evolution

The strategic objectives of foreign aid have evolved over time. USAID was founded during the Cold War with the aim of supporting nations in resisting “communist pressure” and demonstrating that economic growth and political democracy could advance together.

More recently, focus areas have included countering the global influence of nations like China and Russia, addressing humanitarian crises, and promoting global health, including responses to pandemics like COVID-19. The Biden Administration identified responding to climate change, addressing the effects of the COVID-19 pandemic, and combating authoritarianism as cross-cutting priorities for foreign assistance.

The idea that there is a clear separation between promoting U.S. values and advancing U.S. national interests is often rejected. Providing needs-based humanitarian assistance and reducing human suffering can build partnerships and trust that serve longer-term U.S. strategic interests. For example, U.S. support in rebuilding Liberia after its civil war and assisting during the Ebola outbreak helped solidify a partnership that yielded diplomatic benefits over time.

Types of Foreign Aid

U.S. foreign aid is diverse and can be broadly categorized to better understand its specific aims and applications. According to the Council on Foreign Relations and other sources, U.S. foreign aid generally falls into these categories:

Humanitarian Aid

This type of assistance is provided to people in need due to man-made or natural disasters, such as wars, famines, earthquakes, or extreme weather events. It aims to address the immediate, life-saving needs of populations in crisis.

Examples include providing food, shelter, clean water, and emergency medical care. In 2020, the U.S. committed $4 billion in humanitarian assistance to an international partnership for COVID-19 vaccines for low- and middle-income countries. The U.S. Department of State categorizes Humanitarian Assistance as supporting disaster and emergency relief efforts, including programs that save lives, alleviate suffering, and maintain human dignity.

Development Aid

This focuses on long-term economic development in a country or community. The goal is to provide the foundational elements for sustainable growth, enabling people to develop their own businesses and secure ongoing income.

An example is USAID’s 2016 initiative in Bangladesh, partnering with local banks to offer loans to low-income farmers to expand their businesses. This aligns with the State Department’s “Economic Growth” category, which includes areas like climate change adaptation, infrastructure, and environmental programming.

Economic Aid

This category includes broader support for economic stability and policy reforms. The Economic Support Fund (ESF) provides grants to foreign governments to support economic stability. While often used for non-military purposes, ESF grants are sometimes viewed as a way to help key security allies offset military expenditures.

The State Department’s Office of Foreign Assistance broadly categorizes “Economic and Development Assistance” as advancing national security by helping countries meet near-term political, economic, and development needs.

Political Aid

This type of aid supports political stability, democratic institutions, human rights, and good governance. It can fund activities like peace talks, human rights advocacy, judicial reforms, and election monitoring.

For example, USAID provided political development aid to local organizations in Georgia in 2014 to train election monitors. The State Department’s “Democracy, Human Rights and Governance” category reflects assistance supporting the establishment and protection of democratic institutions and values.

Health Aid

This comprises foreign assistance supporting countries in improving the health of their populations, particularly vulnerable groups. Key components include expanding basic health services, strengthening national health systems, and addressing global health issues like HIV/AIDS.

The President’s Emergency Plan for AIDS Relief (PEPFAR) is a prominent example, having provided care to over 20 million people and trained hundreds of thousands of health workers globally.

Education and Social Services Aid

This category includes assistance to nations for sustainable improvements in the well-being and productivity of their populations through investments in education and other social services.

These categories are not always mutually exclusive, and many aid programs have cross-cutting objectives. For instance, an education program might also contribute to long-term economic development and promote democratic values. The complexity of these categories and their interrelations underscores the multifaceted nature of U.S. foreign assistance.

Who Manages Foreign Aid?

The administration of U.S. foreign aid is a complex endeavor involving multiple government departments and agencies, each with specific roles and expertise. While USAID is often the most recognized face of American foreign aid, it is part of a broader network.

USAID

Traditionally the lead U.S. government agency for administering civilian foreign aid, USAID was founded in 1961. It has historically managed a significant portion of the U.S. foreign aid budget, accounting for over half in 2023. USAID’s work spans various sectors, including disaster relief, poverty reduction, global health, education, democracy promotion, and economic growth.

Recent reports in 2025 indicate a significant restructuring and potential dismantling of USAID under the Trump administration, with many of its functions, particularly humanitarian assistance and global health support, being “realigned” or shifted to the Department of State. This has led to widespread concern about the impact on ongoing programs, funding continuity, and the overall effectiveness of U.S. development and humanitarian efforts.

Department of State

The Secretary of State has overall responsibility and authority for the direction and coordination of most U.S. foreign assistance, including aid authorized under the Foreign Assistance Act of 1961 and the Arms Export Control Act. The Department’s Office of Foreign Assistance was created in 2006 to improve strategic coordination and oversight of all foreign assistance funding, working closely with USAID.

With the reported changes to USAID, the State Department’s role in directly managing aid programs, particularly humanitarian and global health initiatives through bureaus like the Bureau of Population, Refugees, and Migration, is expected to expand significantly. The State Department also manages various specific aid programs, including those related to global health, economic support, democracy, and refugee assistance.

Other Key Agencies

Department of Agriculture: Manages international food aid programs, such as Food for Peace.

Department of Health and Human Services: Involved in global health initiatives.

Department of the Treasury: Manages certain financial assistance programs, contributions to international financial institutions, and debt restructuring efforts.

Millennium Challenge Corporation: An independent U.S. foreign assistance agency established in 2004, providing large-scale grants to countries that demonstrate a commitment to good governance, economic freedom, and investments in their citizens.

Peace Corps: An independent agency that sends American volunteers abroad to work on development projects.

Department of Defense: While primarily associated with military assistance, the DoD also administers certain foreign assistance programs, particularly those with a security or humanitarian component, such as disaster relief or capacity building of partner security forces.

Historically, the State Department and USAID have comprised more than 90% of the U.S. International Affairs Budget. The effective coordination among these various agencies is critical for the coherent and efficient delivery of U.S. foreign aid. However, the significant structural changes reported in 2025 introduce new dynamics and potential challenges to this established system.

Foreign Aid Spending and Recipients

As previously noted, U.S. foreign aid constitutes a small fraction of the federal budget, around 1%. In FY 2023, total foreign aid obligations were approximately $79.5 billion. Of this, 75% was designated for economic purposes, and 25% for military purposes. Disbursements in FY 2023 were $71.9 billion, representing 1.3% of total federal spending.

The U.S. provides assistance to a large number of countries; in FY 2022, approximately 180 countries and territories received U.S. aid. For FY 2023, 173 of the 196 countries recognized by the State Department received aid.

Top Recipients in FY 2023

Ukraine: $16.6 billion (primarily due to the ongoing conflict with Russia)
Israel: $3.3 billion
Ethiopia: $1.8 billion

These three countries collectively accounted for 30% of all U.S. foreign aid spending in FY 2023. Ukraine alone received more aid than the bottom 159 aid-receiving countries combined in that year.

Some aid also goes to entities not recognized by the U.S. as sovereign countries, such as the West Bank and Gaza ($112.0 million in FY 2023) and Taiwan ($136.1 million in FY 2023).

Top Cumulative Recipients (FY 2001–2023)

Afghanistan: $145.9 billion
Israel: $91.2 billion
Iraq: $89.4 billion
Egypt: $49.2 billion
Jordan: $30.4 billion

Ukraine also features prominently in this period with $41.3 billion, largely due to recent escalations.

The list of top recipients shifts over time, reflecting evolving U.S. strategic priorities, international crises, and policy initiatives. Typically, top recipients are strategic allies, countries experiencing humanitarian crises, key counterterrorism partners, or global health focus countries.

The allocation of foreign aid is not arbitrary; it is deeply intertwined with U.S. foreign policy objectives. For example, significant aid to Israel and Egypt has historically been linked to promoting peace and stability in the Middle East and supporting key security partnerships. Aid to Afghanistan and Iraq was heavily influenced by U.S. military involvement and nation-building efforts in those countries. The surge in aid to Ukraine is a direct response to Russia’s invasion and U.S. efforts to support Ukrainian sovereignty and security.

The data on foreign aid, including amounts, recipients, and purposes, is made publicly available through ForeignAssistance.gov, which aims to provide transparency. However, due to collection and reporting lags from the more than 20 federal agencies involved, it can take up to two years for data to be considered “fully reported,” and numbers can continue to change.

What is U.S. Military Assistance?

U.S. military assistance refers to the provision of defense-related articles, services, training, or financing to foreign countries and international organizations. It is a distinct but sometimes overlapping component of U.S. foreign engagement, primarily aimed at bolstering the security of the United States and its partners, promoting regional stability, and supporting broader U.S. foreign policy and national security objectives.

Defining U.S. military assistance precisely can be challenging, as various terms are used across different government agencies and legislative acts. There isn’t one single, universally accepted definition for “foreign military aid” or “military assistance.”

The U.S. Code authorizes the President to furnish military assistance to friendly countries or international organizations if it is found to strengthen U.S. security and promote world peace. This assistance can include providing defense articles and defense services, assigning U.S. military personnel for noncombatant duties, or transferring funds for the procurement of defense articles and services.

Security Cooperation vs. Security Assistance

The Department of Defense often uses the broader term Security Cooperation, which comprises all DoD activities undertaken to encourage and enable international partners to work with the U.S. towards strategic objectives. Security Cooperation includes all DoD interactions with foreign defense and security establishments, encompassing DoD-administered Security Assistance programs, military-to-military engagements, exercises, and capacity building.

Security Assistance itself is a group of programs, typically authorized under Title 22 of the U.S. Code (governing foreign relations), by which the U.S. provides defense articles, military education and training, and other defense-related services through grants, loans, credit, cash sales, or leases. Security Assistance programs administered by the DoD are considered a subset of the broader Security Cooperation activities.

The Department of State plays a crucial supervisory role, directing U.S. Government security sector assistance programs, including key Title 22 programs like Foreign Military Financing, International Military Education and Training, and Peacekeeping Operations support.

The preference for the term “Security Cooperation” by the DoD, which is more encompassing than “Security Assistance” or “military assistance,” is significant. Security Cooperation includes a wider array of interactions, such as joint military exercises and strategic dialogues, that go beyond the direct provision of material or training.

Goals of U.S. Military Assistance

U.S. military assistance is fundamentally driven by the aim to enhance U.S. national security. This overarching goal is pursued through several interconnected objectives:

Strengthening U.S. National Security

This is the foundational purpose articulated in U.S. law, authorizing assistance to friendly countries when it is determined to bolster U.S. security and contribute to world peace.

Building Partner Capacity

A core tenet of military assistance is to enable partner nations to provide for their own self-defense, manage internal security threats, and participate effectively in multinational operations. This aligns with the broader concept of Security Cooperation and can reduce the need for direct U.S. military intervention, as suggested by strategic approaches that involve burden-sharing with regional partners.

Enhancing Interoperability

A significant goal is to ensure that the military forces of partner nations can operate effectively alongside U.S. forces in coalition environments. This is crucial for joint responses to shared security challenges.

Counterterrorism and Addressing Transnational Threats

Military assistance is frequently used to help partners combat terrorism, illicit drug trafficking, piracy, and other transnational criminal activities that can threaten U.S. interests and global stability.

Supporting Strategic Alliances and Deterrence

Reinforcing alliances, deterring potential adversaries (particularly in the context of strategic competition with powers like China and Russia), and maintaining favorable regional security balances are key objectives. Military assistance signals U.S. commitment to its allies and partners.

Promoting the U.S. Defense Industry

Programs like Foreign Military Financing and direct arms sales contribute to the U.S. defense industrial base, support American jobs, and ensure continued demand for U.S. military technology.

While building partner capacity is a primary objective, it presents a complex challenge. Empowering foreign military forces inherently carries the risk that U.S.-provided capabilities might be misused—for example, in ways that violate human rights or undermine democratic governance—or could inadvertently contribute to regional instability or even coups d’état.

The U.S. government employs mechanisms like the Leahy Laws, which prohibit assistance to foreign security force units credibly implicated in gross violations of human rights unless effective corrective measures are being taken by the host government. However, the effectiveness and consistent application of such safeguards remain subjects of ongoing debate.

This highlights an inherent tension in military assistance policy: the strategic imperative to empower partners versus the imperative to ensure that such power is used responsibly and in alignment with U.S. values and interests. Successful military assistance depends heavily on careful partner selection, robust oversight, and a strong alignment of strategic interests between the U.S. and the recipient nation.

Types of Military Assistance

U.S. military assistance is delivered through a diverse array of programs and mechanisms, each tailored to specific purposes and operating under distinct legal authorities.

Foreign Military Financing

This program primarily provides grants (though loans are also possible) to foreign governments to finance their acquisition of U.S. defense articles, services, and training. These acquisitions are typically made through the Foreign Military Sales system, or, for a limited number of countries, through FMF-financed Direct Commercial Contracts.

FMF aims to ensure partners are equipped to meet common security goals, share burdens in joint missions, enhance regional stability, and improve interoperability with U.S. forces.

International Military Education and Training

IMET provides grants for foreign military personnel and selected foreign civilian officials to attend U.S. military educational institutions and training courses, both in the U.S. and abroad. The program’s goals extend beyond technical military training to include promoting military professionalism, instilling democratic values (such as civilian control of the military and respect for human rights), fostering interoperability, and building long-term relationships with future leaders of partner nations.

Arms Sales

Foreign Military Sales: These are government-to-government sales of U.S. defense articles, services, and training, where the U.S. government acts as an intermediary between the foreign customer and U.S. defense suppliers. FMS cases can be funded by the partner nation’s own funds or through U.S. FMF grants. The FMS program is a significant component of security assistance, with sales amounting to $62 billion in FY 2023.

Direct Commercial Sales: These involve sales of defense articles and services directly from U.S. defense companies to foreign governments or international organizations. Such sales require export licenses from the U.S. Department of State. DCS totaled $157 billion in FY 2023.

The FMF and FMS systems often work in tandem. FMF grants provided by the U.S. government are frequently used by recipient nations to finance purchases through the FMS program. This creates a cycle where U.S. taxpayer funds enable foreign partners to buy U.S.-manufactured defense equipment and services.

While the primary objective is to enhance the security capabilities of partner nations, this mechanism also provides direct economic benefits to the U.S. defense industry and supports domestic employment. This dual benefit—security for the partner and business for U.S. companies—is an important factor contributing to the political and economic underpinnings of these programs.

Peacekeeping Operations Support

The U.S. provides funding to support regional stability operations and multilateral peacekeeping efforts, particularly those not funded by the United Nations. This can include building the capacity of partner nations to participate in peacekeeping missions and supporting counter-terrorism operations, for example, against groups like al-Shabaab in Somalia.

DoD Security Cooperation Programs

The Department of Defense has its own set of authorities, funded primarily through the defense budget (Title 10 of the U.S. Code), to conduct security cooperation activities. These are distinct from the State Department-led Title 22 programs like FMF and IMET. Examples include:

Section 333 Building Partner Capacity: A global train-and-equip authority to build the capacity of foreign security forces.

Joint Combined Exchange Training: Authorizes training deployments for U.S. Special Operations Forces alongside partner nation forces, primarily to train U.S. forces but with incidental benefits to partners.

Ukraine Security Assistance Initiative: A DoD-led initiative to provide security assistance to Ukraine.

Indo-Pacific Maritime Security Initiative: Focuses on enhancing maritime security capabilities of partners in the Indo-Pacific region.

Other programs include Institutional Capacity Building efforts, and various educational and training activities like the State Partnership Program and Regional Centers for Security Studies.

Presidential Drawdown Authority

This authority allows the President to authorize the speedy delivery of defense articles and services directly from Department of Defense stocks to foreign countries and international organizations in response to unforeseen emergencies. PDA has been extensively used to provide rapid military assistance to Ukraine following Russia’s invasion.

Nonproliferation, Anti-Terrorism, Demining

These State Department-managed programs provide assistance for demining, counter-terrorism training for law enforcement, and efforts to prevent the proliferation of weapons of mass destruction.

Who Manages Military Assistance?

The management of U.S. military assistance is a complex interagency effort, primarily involving the Department of State and the Department of Defense, each with distinct but complementary roles.

Department of State

The Secretary of State holds the overall responsibility for the continuous supervision and general direction of Security Assistance programs, ensuring they align with U.S. foreign policy objectives. The State Department determines which countries are eligible for programs like Foreign Military Financing and International Military Education and Training, and allocates the funding amounts for these Title 22 programs.

Within the State Department, the Bureau of Political-Military Affairs is the lead bureau for security assistance policy and oversight. Its Office of Security Assistance specifically manages FMF, IMET, and Peacekeeping Operations funding and policy.

The State Department, through its Directorate of Defense Trade Controls within the PM Bureau, is responsible for licensing Direct Commercial Sales of defense articles and services. Crucially, by law, Department of State approval or concurrence is required for many Department of Defense security cooperation activities to ensure that these programs are consistent with and advance a unified U.S. foreign policy strategy.

Department of Defense

The DoD is primarily responsible for the implementation and execution of most military assistance and security cooperation programs. The Defense Security Cooperation Agency is the principal DoD agency that directs, administers, and provides guidance for the execution of many Security Assistance and Security Cooperation programs, including the implementation of FMF-funded acquisitions, IMET programs, and FMS cases. DSCA acts as the bridge between foreign partners and the U.S. defense acquisition system.

The Military Departments (Army, Navy, Air Force) and the geographic Combatant Commands play significant roles in planning, executing, and managing specific security cooperation activities and training programs in their respective areas of responsibility.

DoD also manages its own security cooperation programs funded under Title 10 of the U.S. Code (the defense budget), which are distinct from, but often complementary to, State Department-led Title 22 programs.

Coordination Challenges

The division of labor—State Department leading on foreign policy guidance and program approval, DoD leading on execution and managing its own Security Cooperation programs—necessitates robust interagency coordination. This relationship is critical: while the State Department legally holds the reins for the overall direction of security assistance to ensure it serves broader U.S. foreign policy, the Department of Defense, with its extensive resources, global presence, and direct engagement with foreign militaries, wields significant influence in the practical implementation and shaping of these security partnerships.

The requirement for State Department concurrence on many DoD-led Title 10 activities is a key mechanism to maintain policy coherence. However, the sheer scale and operational tempo of DoD’s global security cooperation enterprise mean it is an inherently powerful actor in this domain. Any misalignment between diplomatic goals championed by State and military-strategic objectives pursued by DoD can lead to programs that are ineffective or even counterproductive to overall U.S. interests.

Military Assistance Spending and Recipients

Military assistance represents a substantial component of U.S. foreign engagement funding. While precise figures can vary based on definitions and accounting, available data provides a clear picture of its scale and primary beneficiaries.

Overall Budget and Trends

In FY 2023, military assistance accounted for approximately 25% of the total $79.5 billion U.S. foreign aid obligations, which translates to roughly $19.875 billion. The State Department’s Bureau of Political-Military Affairs’ Office of Security Assistance directs approximately $6.5 billion annually in FMF, IMET, and PKO funding. For FY 2020, FMF program funding was around $6.15 billion.

Arms sales represent a much larger financial flow, though these are often funded by the partner nations themselves or financed through loans, rather than being direct U.S. grant aid. In FY 2023, Foreign Military Sales totaled $62 billion, and Direct Commercial Sales reached $157 billion. FMF grants can be used by recipient countries to finance FMS purchases.

Top Recipient Countries

Certain countries have consistently received the bulk of U.S. military assistance, reflecting long-standing strategic partnerships and regional security concerns.

Source: Adapted from official U.S. sources for FY 2020. Note: Afghanistan’s aid context changed dramatically after August 2021.

Israel and Egypt are historically the largest and most consistent recipients of FMF. For FY 2020, Israel was allocated $3.3 billion in military assistance, and Egypt $1.3 billion.

Ukraine has emerged as a top recipient since Russia’s full-scale invasion in 2022, receiving billions in assistance primarily through Presidential Drawdown Authority and the Ukraine Security Assistance Initiative. By early 2025, the U.S. had provided approximately $69.7 billion in military assistance to Ukraine since Russia’s initial 2014 invasion, with $66.9 billion since the 2022 full-scale invasion.

Strategic Rationale for Recipients

The allocation of military assistance is driven by specific U.S. strategic interests:

Israel: Support for Israel’s security is a cornerstone of U.S. Middle East policy, aimed at bolstering a key democratic ally, helping it maintain its Qualitative Military Edge against regional threats (particularly Iran and its proxies like Hamas and Hezbollah), and supporting U.S. geopolitical interests. U.S. aid has been critical for Israel’s defense systems like Iron Dome and David’s Sling.

Egypt: U.S. military aid to Egypt has been a key component of regional stability efforts since the Camp David Accords and the 1979 Egyptian-Israeli peace treaty. It aims to support counterterrorism cooperation and maintain the strategic partnership.

Ukraine: Assistance to Ukraine surged in response to Russian aggression, with the primary goals of helping Ukraine defend its sovereignty and territorial integrity, degrading Russia’s military capabilities, and reinforcing security in Europe.

Jordan: Aid to Jordan supports a key partner in a volatile region, facilitates Israeli-Arab security cooperation, and enhances interoperability with U.S. Central Command forces.

General Strategic Imperatives: Broader considerations include countering global terrorism, containing Iranian influence, managing strategic competition with China and Russia, ensuring freedom of navigation, and supporting coalition partners in various operations.

The long-term, high-volume military assistance provided to countries like Israel and Egypt illustrates the “stickiness” of these security relationships. Decades of aid create deep institutional, technological, and personal ties between the U.S. defense establishment and those of the recipient nations. These partners often become reliant on U.S. equipment, training, and doctrine.

While this sustained engagement can provide the U.S. with significant influence, it also creates a form of path dependency. This can make it challenging to adjust or reduce aid levels even if a partner’s actions become problematic or diverge from U.S. interests, as some research suggests that worsening human rights records have not always led to decreased U.S. military aid.

Furthermore, these long-standing commitments can compete for resources with emerging strategic priorities, such as the focus on great power competition. This inherent inertia in military aid allocations is crucial for understanding why certain countries consistently remain top recipients.

Key Distinctions and Overlaps

While both foreign aid and military assistance are tools of U.S. foreign policy, involve significant resources, and aim to serve U.S. interests, they differ in their core purposes, primary activities, legal underpinnings, and the agencies that manage them. However, there are also important areas of overlap where the lines can blur.

Core Purpose and Intent

Foreign Aid: The primary intent of most foreign aid is to foster socio-economic development, alleviate human suffering, and promote better governance in recipient countries. This includes objectives like reducing poverty, improving health and education outcomes, strengthening democratic institutions, responding to humanitarian crises, and promoting sustainable economic growth. While these efforts ultimately serve U.S. strategic interests by contributing to a more stable and prosperous world, the direct activities are typically focused on improving conditions within the partner nation.

Military Assistance: The core purpose of military assistance is to enhance the defense and security capabilities of foreign partners, directly supporting U.S. military and national security objectives. This involves strengthening alliances, improving partners’ abilities to defend themselves and contribute to coalition operations, countering shared threats, and maintaining regional stability from a security perspective.

Legal and Funding Mechanisms

Foreign Aid: Much of U.S. foreign aid is authorized under the Foreign Assistance Act of 1961, as amended. Funding is primarily appropriated through annual Department of State, Foreign Operations, and Related Programs legislation. Specific types of aid, like food assistance or development finance, may have their own authorizing statutes.

Military Assistance: Key military assistance programs such as Foreign Military Financing and International Military Education and Training are also authorized under the Foreign Assistance Act (specifically, Title 22 of the U.S. Code, which governs foreign relations). Arms sales, including Foreign Military Sales and Direct Commercial Sales, are primarily governed by the Arms Export Control Act.

A significant distinction arises with Department of Defense-led security cooperation programs. These are often authorized and funded under Title 10 of the U.S. Code (which governs the Armed Forces) and are part of the defense budget. This “Title 10 versus Title 22” distinction is more than an administrative technicality.

Title 22 programs are generally designed with the State Department in the foreign policy lead. In contrast, Title 10 programs are typically more directly tied to DoD’s military-strategic objectives and foster direct military-to-military engagement. This dual-track system can sometimes lead to differing priorities, distinct oversight mechanisms, and varying levels of diplomatic involvement.

Implementing Agencies

Foreign Aid:

• USAID: Traditionally the lead agency for most U.S. development and humanitarian assistance (Note: Recent reports in 2025 indicate significant restructuring and transfer of USAID functions to the State Department)
• Department of State: Oversees foreign policy aspects of aid, manages certain aid programs directly, and, with the reported USAID changes, is taking on more direct management of humanitarian and development functions
• Millennium Challenge Corporation: Provides large grants for poverty reduction through economic growth to countries meeting governance criteria
• Other agencies like the Department of Agriculture (food aid) and Treasury (international financial affairs) also play roles

Military Assistance:

• Department of State: Leads on policy, determines FMF/IMET recipients and amounts, licenses commercial arms sales, and provides overall foreign policy direction and oversight for security assistance
• Department of Defense: Primarily responsible for program implementation. The Defense Security Cooperation Agency manages the execution of FMF, IMET, FMS, and many Title 10 security cooperation programs

Security Assistance as an Overlapping Concept

The term “Security Assistance” itself often serves as a bridge or an overlapping category. As defined by the State Department and in legislation like the Foreign Assistance Act, Security Assistance encompasses a broad range of programs that support security goals. This clearly includes FMF and IMET, which are overtly military in nature. However, Security Assistance can also include programs like:

• International Narcotics Control and Law Enforcement: Assistance to foreign partners to combat drug trafficking, transnational crime, and strengthen law enforcement institutions
• Nonproliferation, Anti-terrorism, Demining and Related Programs: Support for efforts to prevent the spread of WMDs, combat terrorism, and clear landmines and other explosive remnants of war
• Economic Support Fund: While primarily economic, ESF can be used to support the security and stability of key strategic partners

The DoD’s even broader term, “Security Cooperation,” further illustrates this overlap, as it includes all DoD interactions with foreign defense establishments, some of which might have developmental or diplomatic implications beyond purely military ones.

This means there isn’t always a rigid dividing line. Some activities traditionally considered “foreign aid” (such as governance programs aimed at security sector reform, or economic aid to a country facing security threats) directly contribute to security objectives. Conversely, some “military assistance” (like IMET programs that include human rights training or disaster response preparedness) can have positive developmental or governance outcomes.

Smart Power Integration

The recognition of these overlaps and interdependencies has led to the promotion of “Smart Power” as a guiding principle in U.S. foreign policy. Smart Power emphasizes the strategic integration and appropriate application of all tools of American statecraft—often summarized as the “3 Ds”: Defense (military action and assistance), Diplomacy (State Department-led engagement), and Development (foreign aid).

The idea is that U.S. foreign policy is most effective when these elements work in concert, reinforcing each other, rather than operating in isolation or, worse, at cross-purposes. Foreign aid is often described as a tool of “soft power,” complementing the “hard power” associated with military capabilities. Military assistance, particularly programs like IMET that foster relationships and understanding, can also have soft power dimensions.

An effective national security strategy seeks to blend these tools to achieve U.S. objectives efficiently and sustainably.

Debates and Effectiveness

Both foreign aid and military assistance are subjects of ongoing debate regarding their effectiveness, efficiency, and overall impact on recipient countries and U.S. interests. Assessing their success is complex, as outcomes can be multifaceted and subject to various interpretations.

Arguments for Foreign Aid

Proponents of U.S. foreign aid point to a long history of achievements that have contributed to global health, economic development, humanitarian relief, and the promotion of stability and democratic values.

Evidence of Impact

Lives Saved and Health Improved: The President’s Emergency Plan for AIDS Relief (PEPFAR) is widely lauded for saving over 25 million lives and preventing millions of HIV infections globally. USAID-funded health interventions, such as malaria prevention and vaccine programs, are estimated to have saved approximately 3.3 million lives per year, even without counting the impact of water, sanitation, or family planning programs.

Historically, U.S. foreign assistance was instrumental in global efforts to eradicate smallpox and significantly reduce diseases like polio and river blindness. Significant progress has also been made in maternal and child health, with substantial drops in child and maternal mortality rates in countries receiving assistance.

Economic Development and Poverty Reduction: Foreign aid has supported transformative economic development in various regions. It played a role in the Green Revolution in Asia, which dramatically increased food production. Broader efforts are credited with changing the lives of a billion people by reducing poverty.

Stability and Democracy: Aid has helped war-torn nations like Liberia and Sierra Leone recover from conflict and rebuild. It has also supported democratic transitions and strengthened governance in numerous countries.

Building Partnerships and Trust: Beyond tangible outcomes, foreign aid can foster goodwill and solidify partnerships that yield long-term diplomatic and strategic benefits for the U.S., as seen with U.S. support for Liberia during the Ebola crisis.

Case Studies of Success

PEPFAR: A widely cited success for its massive impact on the global HIV/AIDS pandemic.

Nepal’s Earthquake Preparedness: Years of USAID investment in disaster preparedness, including earthquake-resistant construction and emergency response capacity building, significantly improved Nepal’s ability to respond to the devastating 2015 earthquakes. This highlights the value of long-term development aid in building resilience.

Sierra Leone’s Post-Conflict Reconstruction: Considered a relative success story in progressing from devastating civil war to greater stability, with international aid playing a supportive role.

Criticisms of Foreign Aid

Despite these successes, U.S. foreign aid faces persistent criticisms regarding its effectiveness, efficiency, and alignment with development goals versus U.S. national interests.

Effectiveness and Waste

A common critique is that foreign aid efforts have often been ineffective, wasteful, or have not achieved their intended long-term objectives. Some argue that funds could be better used to address domestic priorities or reduce the federal deficit. Monitoring and evaluation systems have historically been criticized as weak, often focusing more on tracking expenditures than on measuring actual impact and learning from successes and failures.

Coordination Problems and Bureaucracy

The U.S. foreign aid system involves numerous agencies, which can lead to fragmentation, duplication of effort, or programs working at cross-purposes. Heavy bureaucracy, extensive earmarks (congressionally mandated spending for specific purposes), and complex procedural rules can slow down aid delivery and increase administrative costs. There can also be a lack of flexibility from Congress to tailor aid types and levels to the specific needs and contexts of recipient countries.

Serving National Interests over Development

Critics argue that aid is often allocated based on the donor’s strategic or commercial interests rather than purely on the development needs of recipient countries. The Cold War era saw instances where aid was provided to autocratic regimes primarily to secure geopolitical alignment, with questionable developmental benefits, such as aid to Mobutu Sese Seko in Zaire.

Impact of Funding Cuts and Policy Shifts

The reported dismantling of USAID and significant funding cuts in 2025 have raised alarms about severe negative consequences. These changes are predicted to halt essential services, lead to layoffs of experienced personnel, and jeopardize global progress in health (e.g., HIV/AIDS treatment, maternal and child health), education, food security, and humanitarian response capabilities in crisis zones like Somalia, Sudan, the Democratic Republic of Congo, and Afghanistan.

Such disruptions risk reversing decades of development gains and could undermine U.S. global leadership and influence.

Challenges in Crisis Contexts

Operating in countries affected by conflict and fragility presents unique challenges. The Humanitarian-Development-Peace nexus framework attempts to bridge short-term relief with long-term resilience-building and peace efforts. However, case studies like Haiti and Iraq reveal failures stemming from overly ambitious projects, poor interagency and donor coordination, and insufficient investment in local capacity, often leading to the creation of parallel aid systems that are unsustainable once external funding diminishes.

The Foreign Aid Paradox

The coexistence of compelling success stories and valid, serious criticisms creates a paradox in evaluating foreign aid. This complexity arises because foreign aid is not a monolithic entity. Its effectiveness varies enormously depending on the specific program, the sector (e.g., health interventions often show more easily measurable results than democracy promotion), the country context (governance, stability, local capacity), and the quality of implementation.

The “success” narrative often highlights tangible, measurable outcomes, particularly in global health. The “failure” narrative may arise from difficulties in achieving broader, more complex goals like large-scale economic transformation or democratic consolidation, or from instances of corruption and inefficiency.

Furthermore, when aid is heavily driven by the donor’s strategic interests, it may not always align with optimal development practices for the recipient. The ongoing challenge for policymakers is to learn from both successes and failures, scale up effective interventions, and reform or discontinue those that are not working—a task complicated by the multiple, and sometimes conflicting, objectives that foreign aid is expected to serve.

Arguments for Military Assistance

Proponents view military assistance as an indispensable tool of U.S. national security and foreign policy, crediting it with strengthening allies, deterring adversaries, and enabling effective coalition operations.

Enhanced Partner Capabilities

A primary argument is that military assistance enables partner nations to better defend themselves and contribute to regional and global security, thereby sharing the burden of maintaining stability.

Successful Coalition Operations

Programs like IMET and FMF are seen as enhancing the interoperability of partner militaries with U.S. forces, which is crucial for the success of joint missions and coalition efforts.

Deterrence and Stability

By strengthening the defense capabilities of allies and partners in key regions, military assistance can contribute to deterring aggression and maintaining regional stability.

Case Studies of Success

Ukraine’s Defense Against Russia: The extensive U.S. military assistance provided to Ukraine since 2022 is widely credited with enabling the country to effectively resist Russia’s full-scale invasion and defend its sovereignty. This is often cited as a prime example of military aid achieving critical strategic objectives.

Colombia: U.S. security assistance, as part of Plan Colombia, is often highlighted for its role in helping the Colombian government combat drug cartels and insurgent groups like the FARC, and in supporting institutional reforms within the Colombian military and security sector.

Jordan: Long-term U.S. military assistance has been instrumental in building Jordan’s defense capabilities, particularly for border security in a volatile neighborhood, and enhancing its role as a key U.S. security partner in the Middle East.

Criticisms of Military Assistance

Despite its strategic rationale, U.S. military assistance has a mixed track record and faces significant criticism regarding its effectiveness, its potential to fuel human rights abuses, its support for undemocratic regimes, and its role in regional instability.

Mixed Track Record and Ineffectiveness

The overall impact of military assistance is varied, and there is still a limited understanding of which approaches work best under what conditions. Large-scale and costly efforts to build partner military capacity in countries like Afghanistan and Iraq ultimately saw those forces collapse or perform poorly, raising serious questions about the sustainability and effectiveness of such assistance.

Similarly, security assistance to some countries in Africa has been criticized for failing to prevent or end terrorist threats and, in some cases, contributing to greater instability.

Human Rights Abuses and Support for Authoritarian Regimes

A major concern is that U.S.-provided weapons and training have been used by partner forces to suppress internal dissent and commit human rights abuses. Research indicates that increased U.S. military aid has, in some contexts, been associated with an elevated incidence of human rights abuses in recipient countries, and that worsening human rights records have not consistently led to a reduction in U.S. aid.

While the Leahy Laws are designed to prevent assistance to units credibly implicated in gross violations of human rights, debates continue about their consistent enforcement and potential loopholes.

Fueling Instability and Arms Races

Critics argue that military aid can decrease incentives for good governance in recipient states by making regimes less dependent on their populace and providing them with more effective tools of repression. There are also concerns that large influxes of military hardware can trigger regional arms races and escalate tensions.

Furthermore, there have been instances where military officers who received U.S. training have subsequently been involved in coups d’état, particularly in several African nations, raising questions about the impact of such training on democratic norms and civilian control of the military.

The Military-Industrial Complex

Some critics contend that U.S. military assistance policies are unduly influenced by the military-industrial complex (the network of defense contractors, Pentagon officials, and supportive lawmakers), which may prioritize arms sales and political benefits over sound strategic planning and the actual security needs of the U.S. or its partners. This can lead to overspending on defense and an emphasis on military solutions over diplomatic or developmental ones.

Effectiveness of Lethal vs. Non-Lethal Aid

There is a growing body of research and practitioner observation suggesting that the type of military assistance matters significantly. Providing lethal aid (weapons and combat training) without accompanying non-lethal assistance (such as advising on defense institution building, logistics, human resources management, and adherence to the rule of law) may do more harm than good.

Success in military assistance is often linked to two key factors: a strong alignment of strategic interests between the U.S. and the partner, and a genuine commitment by the partner to build robust, accountable, and effective defense institutions.

The Moral Hazard Problem

The provision of military assistance can create a “moral hazard.” When a recipient government receives substantial external security support, it may become less reliant on its own population for legitimacy and resources, and less accountable to its citizens.

This can reduce incentives for good governance, democratic reforms, or respect for human rights, and may even embolden regimes to engage in repressive behavior or pursue risky foreign policies, knowing they have a powerful external backer. The finding that increased U.S. military aid has, in some studies, correlated with a deterioration in human rights conditions lends support to this concern.

This highlights a critical unintended consequence: military assistance intended to enhance stability could inadvertently undermine democratic development or exacerbate internal or regional conflicts if not managed with strong conditionality, a clear focus on good governance, and a realistic assessment of the partner’s commitment to shared values.

Common Acronyms

To navigate the complex world of U.S. foreign engagement, it’s helpful to be familiar with some common acronyms:

The Legal and Congressional Role

The provision of both foreign aid and military assistance by the United States is not an arbitrary executive function but is deeply rooted in a legal framework established and overseen by the U.S. Congress. Congress plays a critical role in authorizing programs, appropriating funds, and conducting oversight of how these resources are used.

Key Legislation

The Foreign Assistance Act of 1961: This landmark legislation serves as the cornerstone authorizing framework for most modern U.S. foreign assistance activities. The FAA established U.S. foreign assistance policy and authorized appropriations for a wide range of programs, including economic development, voluntary contributions to international organizations, and selected military assistance programs like FMF and IMET.

Historically, Congress typically debated and reauthorized the FAA every two years until 1981. However, the last comprehensive reauthorization of the FAA occurred with the International Security and Development Cooperation Act of 1985, which authorized programs for FY 1986 and 1987. Since then, a full reauthorization has not been enacted.

This has led to criticisms that the Act is outdated, reflecting Cold War priorities and containing a bewildering array of 33 different goals, 75 priority areas, and 247 directives, which can create administrative burdens and diffuse programmatic focus. In the absence of regular comprehensive reauthorizations, foreign assistance policymaking has often shifted to annual appropriations bills.

Other Key Authorizing Legislation:

• Arms Export Control Act: The primary law governing the sale, lease, and licensing of U.S. defense articles and services to foreign countries and international organizations, including Foreign Military Sales and Direct Commercial Sales
• Agricultural Trade Development and Assistance Act of 1954: Also known as Food for Peace, this act authorizes U.S. international food aid programs
• Millennium Challenge Act of 2003: Established the Millennium Challenge Corporation and authorizes its economic growth initiatives
• Title 10, U.S. Code: Contains various authorities for the Department of Defense to conduct security cooperation activities and provide certain types of assistance using defense appropriations

Congressional Authorization, Appropriation, and Oversight

Congress exercises its constitutional “power of the purse” and its legislative authority to shape U.S. foreign aid and military assistance through a multi-stage process:

Authorization

Legislation passed by Congress that establishes, continues, or modifies federal programs or agencies and sets out the policies and restrictions governing them. Authorization bills (like the FAA or AECA) typically recommend funding levels but do not actually provide the money. The House Foreign Affairs Committee and the Senate Foreign Relations Committee have primary jurisdiction over foreign assistance authorization legislation.

Appropriation

Legislation passed by Congress that provides the actual budget authority, allowing federal agencies to incur obligations and make payments out of the U.S. Treasury. Foreign aid and many military assistance programs (like FMF and IMET) are primarily funded through the annual Department of State, Foreign Operations, and Related Programs appropriations bill.

DoD-led security cooperation programs are typically funded through the defense appropriations bill. In the absence of regular FAA reauthorizations, SFOPS appropriations laws have become a significant vehicle for foreign assistance policymaking, often including provisions that waive statutory reauthorization requirements to allow programs to continue.

Oversight

Congress is responsible for overseeing the implementation of foreign aid and military assistance programs to ensure they are effective, efficient, and consistent with U.S. law and policy objectives. Oversight mechanisms include:

Hearings and Investigations: Committees can hold hearings to question administration officials and examine program performance.

Reporting Requirements: Legislation often mandates that executive branch agencies provide regular reports to Congress on program activities, spending, and outcomes.

Notifications: For certain arms sales (under AECA) and assistance programs, the executive branch is required to formally notify Congress before proceeding, giving Congress an opportunity to review and potentially block the action.

Audits and Evaluations: Congress relies on reports and investigations from the Government Accountability Office and agency Inspectors General to identify problems and recommend improvements.

Conditions and Restrictions: Congress often includes conditions, restrictions, or earmarks in authorization and appropriations legislation to direct how funds can (or cannot) be used, or to link assistance to certain policy actions by recipient countries (e.g., human rights improvements). The Leahy Laws are a prominent example of such a restriction.

The dynamic between the executive branch (which implements foreign policy) and the legislative branch (which authorizes, funds, and oversees it) is a central feature of how U.S. foreign aid and military assistance are managed. Congressional engagement is critical for ensuring accountability and aligning these programs with the broader interests and values of the American people.
