01 · The brief
Plain-English summaryWhat this bill actually does

The bill would terminate U.S. membership in the United Nations, repeal the statutes authorizing U.S. participation, close the U.S. Mission to the UN, and withdraw from the UN Headquarters Agreement. It prohibits any U.S. funding or participation in UN bodies, peacekeeping, and related conventions, strips diplomatic immunities for UN personnel in the United States, repeals the statute authorizing U.S. participation in the World Health Organization, and requires Senate advice and consent for any future reentry with a withdrawal reservation.

Why people may split

Global health: WHO participation repeal vs maintaining coordination

Watch point

Requires a simple majority but is a dramatic foreign-policy reversal with broad institutional opposition and partisan polarization.

The bill would terminate U.S. membership in the United Nations, repeal the statutes authorizing U.S. participation, close the U.S. Mission to the UN, and withdraw from the UN Headquarters Agreement.

Passage8/100

Extensive, high‑salience rollback of long-standing treaty commitments with few compromise features; historically unlikely to clear both chambers and survive legal/foreign-policy pushback.
