Over the last month, nuclear tensions have been heating up. In late October, Vladimir Putin claimed two achievements: the successful test of a nuclear-powered missile known as Burevestnik and the initial test of an unmanned nuclear-powered submarine known as Poseidon. Both systems theoretically have unlimited range, and both are capable of hosting nuclear warheads. Shortly thereafter, President Donald Trump announced that the United States would resume nuclear testing on an equal basis with Russia and China.



This week on Brussels Sprouts, concerns around the world of a revived nuclear arms race are growing. Between Putin’s nuclear testing, inflamed rhetoric from President Trump, and the looming expiration of the New START Arms Control Treaty between Russia and the United States in February 2026, the mounting evidence paints a concerning picture.



To discuss this and more, the Center for a New American Security is very pleased to welcome Corey Hinderstein and Jon Wolfsthal to Brussels Sprouts. 



Corey Hinderstein is vice president of studies at the Carnegie Endowment for International Peace and is responsible for the Technology, Sustainability, and Nuclear Policy Programs.



Jon Wolfsthal is the director of Global Risk at the Federation of American Scientists and a CNAS adjunct senior fellow.
