HALT Act of 2025 seeks to reduce nuclear threats by halting nuclear tests and promoting global nuclear freeze.

The HALT Act of 2025 aims to reduce and eliminate threats posed by nuclear weapons to the United States. It establishes U.S. policy to lead international negotiations for a global nuclear freeze, halting the testing, deployment, and production of nuclear weapons. The Act prohibits the use of funds for any explosive nuclear weapons test that produces a yield until certain conditions are met, including agreements on on-site inspections and verification measures. It also emphasizes the importance of the Comprehensive Nuclear-Test-Ban Treaty and the need for a verifiable Fissile Material Treaty.
