On January 3, 2026, 150 U.S. aircraft struck military installations in Caracas while Delta Force operators captured President Nicolás Maduro. The administration called it law enforcement, not war. This operation—and the threats now aimed at Iran—reveal how completely the executive branch has taken over the power to start wars, which the Constitution assigns to Congress alone.

The Constitution assigns Congress the power to decide when America goes to war. Article II makes the chief executive commander-in-chief of forces that the legislature has authorized. James Madison told the Constitutional Convention that giving one person both powers would create a prince, not a head of state.

For about 125 years, that design held. Leaders from Washington through McKinley generally asked the legislature before committing to significant military action. Even when they pushed boundaries—Polk maneuvering the country into war with Mexico, for instance—they operated within a framework where legislative involvement remained the formal requirement.

Then came the twentieth century and executives who discovered that “emergency” and “national security” could justify almost anything. Harry Truman sent forces to Korea in 1950 without a declaration of war. His successors expanded the precedent. By Vietnam, the White House stopped asking the legislature for permission.

The legislature tried to fix this in 1973 with the War Powers Resolution. The executive must consult the legislature before introducing forces into hostilities, report within 48 hours, and terminate operations after 60 days without explicit authorization.

Every administration since has ignored it.

Operation Absolute Resolve in Venezuela

On January 3, 2026, the administration conducted Operation Absolute Resolve: 150 aircraft struck military installations in Caracas while Delta Force operators captured Nicolás Maduro. The administration called it law enforcement, not war.

The legal theory went like this: Maduro faced U.S. drug trafficking charges, so apprehending him was a law enforcement operation that happened to require the military. Therefore, the War Powers Resolution required notification—except the administration claimed it didn’t apply. Therefore, no legislative authorization needed.

Curtis Bradley at the University of Chicago said it’s unclear whether the Constitution allows this. He noted that under international law, “the use of military force against another nation is not allowed except in self-defense in response to an armed attack, and Venezuela had not attacked the United States.” International lawyer Geoffrey Robertson was more direct: it was an illegal military attack on another country.

Six days later, the Senate advanced a war powers resolution to block further military action in Venezuela without approval. Five Republicans joined all Democrats. The vote was 52-48.

The White House Office of Management and Budget announced the President would veto it.

Military Options Without Ground Troops

When the administration says it will hit Iran “where it hurts” without ground troops, it’s describing an arsenal that previous generations could only imagine.

In June 2025, Operation Midnight Hammer hit three Iranian nuclear sites using B-2 stealth bombers with special bombs designed to penetrate underground bunkers—the first operational use of that weapon—and Tomahawk cruise missiles from submarines. The bombers flew the longest B-2 mission since 2001, flying without communicating and refueling in the air to avoid being detected.

Drones can maintain sustained pressure while minimizing risk to American personnel. They’ve become routine in operations across multiple continents.

Special operations forces represent another category. Special forces soldiers who sneak into countries to capture people or gather information don’t count as “boots on the ground” in the current lexicon, even though they’re literally American military personnel on foreign soil in combat situations.

The U.S. Navy could stop Iranian ships from leaving or entering the Persian Gulf, disrupting oil sales and naval operations. Cyber operations can damage military command systems, communications infrastructure, or economic targets without any physical presence at all.

Military action provokes retaliation. Iran has ballistic missiles, drones, proxy militias in Iraq and Syria, and the capacity to attack American forces stationed throughout the Middle East and Gulf region. The idea that airstrikes remain contained because no American infantry deploys ignores how escalation works.

The Iran Situation

Protests erupted across Iran starting December 28, 2025, initially over economic conditions—Iran’s currency losing value rapidly—but quickly evolving into calls for regime change. Authorities responded with a nationwide internet blackout, live ammunition, and mass arrests. Rights groups reported between 42 and 65 deaths in the first two weeks and over 2,000 arrests.

The warning followed: if Iranian authorities “start killing people,” the U.S. would get involved. Trump told reporters Iran would “have to pay hell” for violent repression and that America had “fighters for every possible situation.” Secretary of State Marco Rubio expressed support for Iranian protesters while the administration remained deliberately unclear about what the U.S. would do.

Public warnings encourage protesters by suggesting American support is coming. But they also box in the White House—if Iranian security forces kill more protesters and Trump doesn’t act, American credibility takes a hit. If he does act, he’s committing to military operations against a country that hasn’t attacked the United States. Internal protests provide no legal justification under either international law or the founding document.

The UN human rights chief issued a statement of concern. The EU, France, Britain, and Germany condemned excessive force. None of that provides legal cover for American military strikes, which would violate the UN Charter as clearly as the operation in Caracas did.

Congressional Authority and Constraints

Senator Tim Kaine, who co-sponsored the war powers resolution on Venezuela, laid out what’s at stake. The administration has threatened operations to protect Iranian protesters, enforce a Gaza ceasefire, battle terrorists in Nigeria, seize Greenland or the Panama Canal, or suppress Americans peacefully assembling. “Congress has not authorized any of these dangerous potential operations, which risk destroying alliances and relationships that have long kept the American people safe.”

The legislature has several theoretical tools: refusing to appropriate funds for unauthorized operations, conditioning aid on consultation, conducting oversight hearings, passing war powers resolutions. The problem is that all of these require either two-thirds voting to override a veto or White House cooperation that isn’t forthcoming.

Most Republican senators won’t support war powers restrictions. Senate Majority Whip John Barrasso opposed the resolution on Venezuela, arguing it “does not make America stronger. It makes America weaker and less safe.”

Senator Rand Paul, one of the five Republican supporters, made the case plainly: “Bombing another nation’s capital and removing their leader is an act of war, plain and simple. No provision in the Constitution provides such power to the presidency.” He warned that failing to assert the legislature’s role would leave the country “run by emergency.”

Paul is a minority within his own caucus. His appeals to constitutional principle haven’t mobilized broader Republican support for rules that would limit the White House’s ability to start wars.

Executive Advantages in War Powers

The executive branch has systematic advantages that make legislative war powers almost impossible to enforce. It controls the military and intelligence apparatus. It can act swiftly while the legislature debates. It can conduct operations in secrecy while the legislature operates in public. It can call military attacks something else to avoid legal rules. And it can veto any legislation attempting to constrain it.

Alexander Hamilton identified these advantages in Federalist 70: “decision, activity, secrecy, and dispatch.” He thought they justified a unitary executive. What he didn’t anticipate was that these same qualities would enable the White House to effectively amend the founding document through practice, establishing precedents that the legislature couldn’t reverse.

Operation Absolute Resolve succeeded militarily with minimal American casualties. That success becomes its own justification for future operations under similar theories. Political scientist Oscar Berry notes that “a system in which one person can authorize the U.S. military to engage in acts of war is not what the founders had in mind.” But what the founders had in mind matters less than what the executive branch can do.

The Monroe Doctrine and International Precedent

The administration framed Operation Absolute Resolve in terms of a modernized Monroe Doctrine—which was called the “Donroe Doctrine”—asserting American preeminence in the Western Hemisphere. Political scientist Paul Poast suggests Trump is “going to be a great 19th-century U.S. President” in his explicit invocation of the Monroe Doctrine. He notes that while “the U.S. has long maintained dominance in the region,” there is now “a fixation on the hemisphere and a willingness to threaten and apply force at a scale that has not been seen in decades, even in a century.”

Chinese and Russian officials have seized on this conduct as evidence of American hypocrisy. The rules-based international order, they argue, applies selectively to American adversaries while the U.S. exempts itself. It’s hard to argue with them when the U.S. conducts military operations that violate the UN Charter and then claims law enforcement exceptions.

If the White House can conduct military operations by simply calling them something other than war, then the system of checks and balances no longer works. If the U.S. can bomb other countries’ capitals and capture their leaders while claiming law enforcement authority, then international law no longer applies equally to all nations.

The Constitutional Process and Its Bypass

The founding document provides a mechanism for deciding when to use military force: the legislature authorizes it through a process that requires hearings, committee deliberations, floor debates, and roll call votes that establish public records. This process necessarily involves public discourse about military action and its costs.

Contemporary practice bypasses this entirely. Operations are conducted and the legislature is dared to stop them retroactively. When asked why the administration didn’t seek authorization for the operation in Caracas, Secretary of State Rubio offered progressively weaker justifications: it wasn’t an invasion, the legislature couldn’t be trusted with sensitive information, and emergency circumstances prevented consultation despite no emergency.

Neither the legislature nor the courts have developed effective mechanisms to enforce constitutional war powers against a determined executive. Federal courts refuse to get involved, saying these are political decisions the legislature should make. The White House can act quickly and in secret, then dare the legislature to stop it—a dynamic that systematically favors executive expansion.

American citizens exercise effectively no control over decisions to employ military force. The operations are conducted in their name, the consequences affect their foreign policy interests, but they have no meaningful say in those operations.

The Constitutional Crisis

The doctrine of military action “without boots on the ground” isn’t a technical refinement. It’s a constitutional crisis dressed up as strategic flexibility.

It rests on a rhetorical distinction—ground troops versus other military force—that suggests some military actions require no authorization. If accepted, this theory renders the War Powers Resolution meaningless and gives all war-making authority to the executive branch.

It depends on international legal theories that treat military force as permissible absent formal declarations of war, making the U.S. look like a country that ignores international rules.

Military action short of invasion doesn’t avoid the consequences of warfare. Vietnam, Iraq, and Syria show that limited action has consistently escalated beyond initial intentions.

Potential Congressional Remedies

The legislature retains constitutional authority to reassert war powers. It could refuse to appropriate funds for unauthorized operations. It could condition aid on consultation. It could conduct serious oversight. It could pass war powers resolutions with sufficient political will to override vetoes.

The five Republican senators who voted for the resolution on Venezuela demonstrated that bipartisan coalitions can emerge even in a polarized era. But absent sustained pressure and a fundamental shift in Republican attitudes toward executive authority, the legislature will likely keep giving up its ability to decide on wars.

Broader Pattern of Executive Expansion

The shift in war powers represents part of a larger transformation in how the executive branch operates. Over the past century, the White House has accumulated authority across multiple domains through similar mechanisms: acting unilaterally, establishing precedents, and daring the legislature to reverse them after the fact.

Emergency declarations provide one example. The National Emergencies Act of 1976 was supposed to constrain executive emergency powers by requiring review. Instead, the White House has declared dozens of national emergencies, many lasting years or decades. The legislature has never successfully terminated one over objection.

Executive agreements have largely replaced treaties as instruments of international commitment. Treaties require two-thirds Senate approval; executive agreements require nothing. The White House negotiates binding international arrangements that previous generations would have submitted as treaties, and the Senate has acquiesced to its own marginalization.

Regulatory authority has expanded through executive orders and agency rulemaking that often exceed statutory authorization. When courts strike down executive overreach, the White House simply reframes the same policies under different legal theories until finding one that survives judicial review.

Each successful expansion becomes the baseline for the next administration’s claims.

Obstacles to Legislative Pushback

Collective action problems plague any legislative body. Five hundred thirty-five members must coordinate to constrain one chief executive. The White House acts; the legislature reacts. That asymmetry favors executive authority even when majorities oppose specific actions.

Partisan loyalty often trumps institutional loyalty. Members of the administration’s party typically support executive authority when their party controls the White House, then rediscover constitutional limits when the opposition takes office. This partisan cycling prevents the sustained institutional commitment necessary to reclaim legislative prerogatives.

Electoral incentives cut against assertion. Voters hold the White House accountable for foreign policy outcomes but rarely punish individual legislators for failing to constrain executive war powers. Supporting military action carries less political risk than opposing it, especially when operations succeed militarily.

Information asymmetries favor the executive branch. The White House controls intelligence agencies, military briefings, and classified information. When officials claim national security requires secrecy or speed, the legislature lacks independent means to verify those claims. Legislators who challenge executive assertions face accusations of undermining national security.

One symbolic vote that can be vetoed doesn’t constitute institutional reassertion.

International Implications

American constitutional practice shapes international norms. When the United States conducts military operations that violate international law, other nations cite American precedents to justify their own actions.

Russia pointed to NATO’s Kosovo intervention to justify actions in Georgia and Ukraine. China references American military operations when defending its assertiveness in the South China Sea. If the world’s leading democracy exempts itself from international legal constraints, why should other nations comply?

The rules-based international order depends on major nations accepting mutual constraints. That system erodes when the most powerful nation treats international law as applicable to others but not itself. Operation Absolute Resolve—bombing another country’s capital to arrest its leader—sets a precedent that any nation with sufficient military strength could cite.

American credibility in promoting democracy and human rights suffers when the U.S. conducts military operations that its own constitutional system doesn’t authorize. How can America credibly advocate for rule of law abroad when it doesn’t follow its own founding document at home?

The situation with Iran illustrates these tensions. The administration threatens military action to support protesters seeking democratic change. But that military action would itself violate both international law and the constitutional requirement for authorization. The contradiction undermines the legitimacy of American advocacy.

Paths to Reform

Restoring meaningful war powers would require changes across multiple dimensions. Legal reforms alone won’t suffice when the underlying problem is political will.

The legislature could strengthen the War Powers Resolution by eliminating ambiguities the White House exploits. Clear definitions of what constitutes hostilities, automatic funding cutoffs for unauthorized operations, and expedited procedures for war powers resolutions that prevent filibusters would help. But these reforms require passing legislation that will be vetoed and overriding those vetoes with two-thirds majorities.

Appropriations authority offers another avenue. The legislature could prohibit funding for specific operations or require affirmative authorization before funds can be spent on military action. But appropriations bills are complex, must pass regularly, and provide many opportunities for the White House to find workarounds.

Courts could abandon the political question doctrine for war powers cases and adjudicate whether specific military operations exceed executive authority. But federal courts have consistently refused this role, and changing judicial doctrine requires either different judges or sustained pressure that convinces current judges to reconsider.

Public pressure might force change if citizens demanded authorization for military operations. But polling suggests Americans often support military action in the moment, especially when the White House frames operations as necessary for national security. Building sustained public opposition to executive war powers requires changing how citizens think about constitutional structure, not specific military operations.

The most realistic path involves sustained assertion across multiple fronts: passing war powers resolutions even when they’re vetoed, conducting aggressive oversight, using appropriations leverage, and building bipartisan coalitions that transcend partisan loyalty to individual administrations. This requires treating war powers as an institutional prerogative worth defending regardless of which party controls the White House.

The resolution on Venezuela represented a symbolic gesture, not the beginning of systematic reassertion. Until that changes, the White House will continue expanding war powers through unilateral action.
