US HB6508

Requires the President to formally notify NATO of U.S. withdrawal within 30 days of enactment, pursuant to Article 13 of the North Atlantic Treaty

Prohibits all federal funds from being used for U.S. contributions to NATO's common-funded budgets, including the civil budget, military budget, and Security Investment Program

Declares that the act satisfies the congressional authorization requirement under Section 1250A of the FY2024 National Defense Authorization Act for treaty withdrawal

Congressional findings argue NATO's original mission became irrelevant after the 1991 collapse of the Soviet Union and Warsaw Pact, and that eastward expansion has provoked Russia

Findings assert European NATO members have sufficient combined military and economic capacity to counter Russia without U.S. involvement, and that nearly one-third of members fail to meet the 2% GDP defense spending pledge from the 2014 Wales Summit
