A bill to amend the Mutual Security Act of 1954 by declaring that if all NATO countries consent to the accession of Ukraine to NATO membership, the United States will have grounds for withdrawing from the North Atlantic Treaty.

This bill (S 4649) amends the Mutual Security Act of 1954 to establish a specific condition under which the U.S. would have grounds to withdraw from the North Atlantic Treaty. It states that if all NATO members unanimously consent to Ukraine beginning its NATO membership process, the U.S. could immediately withdraw from NATO under Article 13 of the treaty. The bill directly affects U.S. foreign policy commitments by linking NATO membership for Ukraine to a potential U.S. treaty exit. It creates a procedural mechanism for U.S. withdrawal based solely on NATO's collective decision regarding Ukraine's accession.
