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.

In its first public reaction to Trump¡¯s comments, the Kremlin played down their significance and said it was not looking to get into a public argument with him.

Trump said on Friday that he had ordered two nuclear submarines to be moved to ¡°the appropriate regions¡± in response to remarks from former Russian president Dmitry Medvedev about the risk of war between the nuclear-armed adversaries.
