Kremlin spokesman Dmitry Peskov said at a press briefing that Russia “does not wish to become involved” in an exchange with the United States over nuclear threats. His comments came after U.S. President Donald Trump announced he was deploying two nuclear-powered submarines toward Russia in response to social media posts by former President Dmitry Medvedev,

Russia said on Monday that everyone should be "very, very careful" about nuclear rhetoric, responding to a statement by U.S. President Donald Trump that he had ordered a repositioning of U.S. nuclear submarines.
