Trump Orders U.S. to Resume Nuclear Weapons Testing Amid Global Tensions. President Donald Trump has called on U.S. military leaders to restart nuclear weapons testing, saying it's necessary to keep pace with nations like Russia and China. In a social media post ahead of his meeting with Chinese President Xi Jinping in South Korea, Trump said he's directed the Department of War to begin testing "on an equal basis.” He acknowledged the "tremendous destructive power" of nuclear weapons but said he had "no choice" but to modernize America's arsenal. The U.S. has not conducted a nuclear test since 1992, when a moratorium was put in place after the Cold War. The move marks a major shift in decades of U.S. policy and follows Trump's recent criticism of Russia for testing a nuclear-powered missile. He warned that China's nuclear program could rival America's within five years and said the testing process "will begin immediately.” [Instructions: THIS VIDEO MUST NOT BE EDITED FOR LENGTH TO COMBINE WITH OTHER CONTENT]
