HALT Act of 2025

The HALT Act of 2025 directs the U.S. government to negotiate a global nuclear freeze, requiring the President to pursue agreements that would halt testing, production, and deployment of nuclear weapons and delivery systems. Key provisions include seeking a verifiable freeze on nuclear arms development, negotiating numerical limits on weapons (based on 2019 levels), promoting "no first use" policies, and pushing for U.S. ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). The bill aims to build on existing treaties like New START and seeks to engage all nuclear-armed nations in these negotiations. It directly affects U.S. foreign policy and international arms control efforts, though it does not mandate specific cuts or binding limits on other countries.
