# Russia has sought to cool rising nuclear tensions with the United States, after two tests of new Russian nuclear-capable weapons systems prompted US President Donald Trump to order his own nuclear tests. The Kremlin said its testing of nuclear-powered nuclear-capable weapons, the Burevestnik cruise missile and the Poseidon underwater drone, did not constitute a direct test of an atomic weapon. Both countries observe a de facto moratorium on testing nuclear warheads, though Russia regularly runs military drills involving systems that are capable of carrying such weapons.
