By: Xiaodon Liang for Arms Control Today
The U.S. Congress approved a $185 million cut to the defense nuclear nonproliferation budget managed by the National Nuclear Security Administration (NNSA) in a March 14 continuing resolution that funds the federal government through Sept. 30, the end of the 2025 fiscal year.
The resolution transfers those funds instead to the NNSA’s weapons activities budget, bringing it up to $19.29 billion for the remainder of this fiscal cycle. The slashed nonproliferation funding is equal to a 7.2 percent cut. According to an analysis by the Center for Arms Control and Non-Proliferation, the reduction will probably impact NNSA programs on nuclear smuggling, radiological security, export controls, reactor conversion, nuclear materials security and elimination, and research into the impacts of artificial intelligence on nuclear threats.
