In a significant policy shift, former President Trump has directed the Pentagon to resume nuclear weapons testing for the first time in over three decades. The announcement comes just before an anticipated meeting with Chinese President Xi and follows recent missile tests conducted by Russia. Trump stated that the U.S. must match the nuclear capabilities of rival nations like Russia and China, emphasizing the need for immediate action. Experts express concerns about the strategic benefits of such tests, suggesting they may primarily lead to long-lasting environmental damage.
