The Kremlin has tried to calm tensions in a feud between Trump and Medvedev that spiraled into nuclear threats.

The Kremlin warned Monday against “nuclear rhetoric” after President Trump repositioned two nuclear submarines because of what he called “foolish and inflammatory statements” by former Russian president Dmitry Medvedev.

Russia urged caution after Trump claimed he redeployed nuclear subs in response to provocative remarks by a senior Russian official.
