The administration of U.S. President Donald Trump is considering a budget proposal that would eliminate “almost all funding for international organizations like the United Nations and NATO,” the New York Times reported on Monday, citing officials and an internal memo.

The initiative is part of a plan that would see the State Department’s budget reduced by nearly 50%, two unnamed officials told the outlet. It also reportedly suggests curtailing international peacekeeping operations, all of the State Department’s educational and cultural exchanges, and defunding humanitarian assistance and global health programs by more than 50%. It is unclear whether Secretary of State Marco Rubio is on board with the plan.

AP sources have confirmed the proposal but stressed that it must undergo multiple rounds of review before being submitted to Congress for approval. One senior official cited by the agency called the budget outline “aggressive” in its cost-cutting goals.

Responding to questions about the reported plan to cut NATO funding, State Department spokeswoman Tammy Bruce insisted that the U.S. remains fully committed to the military bloc. She stressed, however, that Washington does not see NATO as a tool for waging war, but rather as a deterrent.

“We want to make sure… that the nations in NATO can deliver on the mission of NATO, which is to be a deterrent. It is not to help with wars or to help fight them… NATO was meant to be a collection of entities that would stop the bad actors from doing bad things,” she said.

The Trump administration has repeatedly pushed NATO members to increase their defense spending, arguing the U.S. bears a disproportionate share of the burden. Trump has warned that the U.S. might not defend NATO members who fail to meet spending targets.

On Monday, Vice President JD Vance said Europe cannot remain a “permanent security vassal” of the US, arguing that the current situation benefits neither America nor European countries.
