The United States will begin conducting nuclear weapons testing again after decades of rejecting the practice, President Donald Trump announced Wednesday.

“Because of other countries’ testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis,” Trump wrote in a post on Truth Social. “That process will begin immediately.”
