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. This decision, framed as a response to increasing nuclear capabilities in Russia and China, could potentially escalate nuclear tensions globally. Analysts express concern that this move may provoke retaliation from rival nations and signal the beginning of a new arms race. While Trump insists the tests are necessary to maintain U.S. security, critics warn that resuming testing could lead to chaos and undermine decades of nuclear non-proliferation efforts. As reactions pour in from international leaders, including calls from China to adhere to nuclear testing bans, the world watches closely as the U.S. embarks on this controversial path.
