Alliances and Partnerships

Alliances and partnerships are the formal and informal ties between the United States and other countries that agree to cooperate on security. They include treaty alliances such as NATO, bilateral relationships, joint military exercises, and agreements that set the terms for troops stationed abroad. The president, Congress, the Department of Defense, and the State Department all have roles.

People usually ask what alliance commitments require, how members share costs and responsibilities, what a treaty obligation means in practice, and how alliances differ from trade or economic partnerships.
