Russian President Vladimir Putin has directed his ministers and security officials to prepare proposals for possible nuclear weapons testing, warning the United States of a reciprocal response if it resumes nuclear tests. The move follows U.S. President Donald Trump’s recent order to lift the 1992 moratorium on nuclear testing and instruct the Pentagon to restart tests immediately. During a Security Council meeting on November 5, Putin said that if the U.S. or any signatory of the Comprehensive Nuclear-Test-Ban Treaty resumes testing, Russia will be compelled to respond in kind. He instructed the Foreign Ministry, Defense Ministry, intelligence agencies, and civilian institutions to collect information and develop coordinated plans prioritizing nuclear readiness. Defense Minister Andrei Belousov stated that the U.S. move significantly heightens the military threat to Russia, emphasizing the need to maintain Russia’s nuclear deterrence. Chief of General Staff Valery Gerasimov also warned that delaying action could cost Russia its strategic advantage. Analysts say the renewed nuclear testing rhetoric between Moscow and Washington—both major nuclear powers—marks a dangerous escalation, threatening to further undermine global arms control efforts already weakened by geopolitical tensions over the Ukraine war and sanctions.
