Rep. Thomas Massie has filed HR 6508 to withdraw the United States from NATO, arguing the alliance is outdated, expensive and drags America into foreign commitments. The move has drawn support from like-minded Republicans, including Rep. Anna Paulina Luna, and mirrors Sen. Mike Lee’s companion legislation in the Senate. The plan leans on Article 13 of the North Atlantic Treaty and would direct the president to issue notice of denunciation while blocking funding for NATO’s common budgets.
Representative Massie framed the proposal as a straightforward defense of American interests, saying “NATO is a Cold War relic. The United States should withdraw from NATO and use that money to defend our country, not socialist countries. Today, I introduced HR 6508 to end our NATO membership,” His message taps into a conservative argument about avoiding permanent foreign entanglements and retrenching U.S. resources for homeland defense.
Support for the idea surfaced quickly within the House Republican ranks. Rep. Anna Paulina Luna shared Massie’s post and , writing, “Co-sponsoring this.” That brief but clear endorsement signals appetite among some GOP members for a tougher stance on long-standing security commitments that many see as one-sided.

Massie pointed to the historical origins of NATO to make his case, quoting a press release: “NATO was created to counter the Soviet Union, which collapsed over thirty years ago. Since then, U.S. participation has cost taxpayers trillions of dollars and continues to risk U.S. involvement in foreign wars. Our Constitution did not authorize permanent foreign entanglements, something our Founding Fathers explicitly warned us against. America should not be the world’s security blanket—especially when wealthy countries refuse to pay for their own defense.” That framing ties constitutional concerns to fiscal and strategic priorities.
In the Senate, Sen. Mike Lee has already advanced similar language with his “Not a Trusted Organization Act,” or “NATO Act,” and Massie’s HR 6508 serves as the House companion. Republican momentum for rethinking alliances like NATO rests on arguments about sovereignty, burden sharing and the proper scope of American commitments abroad. These lawmakers favor a strict reading of constitutional limits on permanent foreign obligations.
The text of the treaty itself contains an exit option that proponents of withdrawal want to use. Article 13 of the North Atlantic Treaty stipulates that “After the Treaty has been in force for twenty years, any Party may cease to be a Party one year after its notice of denunciation has been given to the Government of the United States of America, which will inform the Governments of the other Parties of the deposit of each notice of denunciation.” Advocates argue that Article 13 is the lawful, orderly mechanism to end U.S. membership if Congress so chooses.
The draft legislation would invoke that exact escape route and set a tight timetable for action. “Consistent with Article 13 of the North Atlantic Treaty, done at Washington April 4, 1949, not later than 30 days after the date of the enactment of this Act, the President shall give notice of denunciation of the North Atlantic Treaty for purposes of withdrawing the United States from the North Atlantic Treaty Organization,” the proposal declares. The move would be rapid by treaty standards, reflecting urgency from sponsors to shift policy quickly.
Beyond the notice requirement, the measure draws a hard line on funding. “No funds authorized to be appropriated, appropriated, or otherwise made available by any Act may be used to fund, directly or indirectly, United States contributions to the common-funded budgets of the North Atlantic Treaty Organization, including the civil budget, the military budget, or the Security Investment Program,” the text of the measure stipulates. That provision is meant to ensure withdrawal is substantive, not merely symbolic, by cutting off financial support for collective NATO programs.
The proposal has sparked a debate inside the GOP about how to balance alliance commitments with national priorities. Proponents stress constitutional fidelity, fiscal responsibility and the need to prioritize American defense over subsidizing allies. Critics warn of diplomatic and strategic fallout, but the push shows a clear Republican strain pressing for recalibration of U.S. foreign policy and alliance obligations.
