This is a horrible and dangerous idea – unilaterally freezing agreements and treaties while they’re “evaluated” is going back on our word as a country. Foreign governments would almost certainly view a sudden freeze in treaty negotiations as a sign of unpredictability and unreliability in U.S. foreign policy. This would erode trust and harm diplomatic relationships, especially with allies or partners who may have spent years negotiating these agreements. Freezing negotiations on arms control, defense cooperation, or counterterrorism agreements could delay critical measures needed for global security, potentially leaving the U.S. or its allies more vulnerable to threats.
