The NATO Edge Act seeks to significantly restrict the President's ability to withdraw the United States from the North Atlantic Treaty Organization (NATO). It amends existing law, specifically Section 1250A of the National Defense Authorization Act for Fiscal Year 2024, which already requires an Act of Congress or two-thirds Senate consent for such a withdrawal. The bill introduces an additional, stringent condition: any withdrawal would also require that all remaining NATO members not meeting the 2 percent GDP defense spending target explicitly commit to reaching that target within five years. This measure aims to reinforce NATO's collective defense principle and ensure allies contribute adequately. Furthermore, the bill explicitly prohibits the use of any federal funds to support an unauthorized withdrawal from NATO. It also empowers the Senate Legal Counsel or the General Counsel to the House of Representatives to initiate or intervene in judicial proceedings to oppose any withdrawal inconsistent with these new requirements, providing a legal avenue for Congress to challenge presidential actions. The provisions of this Act are set to terminate on September 30, 2033 , at which point the original Section 1250A would be restored.
