The Trump administration has confirmed that the United States will withdraw from 66 international organisations, a move that represents one of the most extensive reductions in American participation in multilateral institutions in decades.
The decision, announced in early January 2026, affects a broad range of bodies spanning climate policy, development, human rights and security cooperation. White House officials said the review was intended to reassess whether US involvement in global organisations continues to serve national interests, signalling a recalibration of foreign policy priorities.
