U.S. President Donald Trump on Friday said he had ordered two nuclear submarines to be positioned in regions near Russia in response to threats from former Russian President Dmitry Medvedev.

“I have ordered two Nuclear Submarines to be positioned in the appropriate regions, just in case these foolish and inflammatory statements are more than just that,” Trump said in a social media post that called Medvedev’s statements highly provocative.

He said he ordered the submarines moved “just in case these foolish and inflammatory statements are more than just that. Words are very important, and can often lead to unintended consequences, I hope this will not be one of those instances.”

Trump and Medvedev, who is deputy chairman of Russia’s Security Council, traded taunts in recent days after Trump on Tuesday said Russia had “10 days from today” to agree to a ceasefire in Ukraine or be hit, along with its oil buyers, with tariffs.

Medvedev on Monday accused Trump of engaging in a “game of ultimatums” and reminded him that Russia possessed Soviet-era nuclear strike capabilities of last resort after Trump told Medvedev to “watch his words.”

Fuck dude, Medvedev is famous for running his mouth and making these kinds of threats about WWIII, but the logical thing to do would be to just “retaliate” by going through with tariffs before the 10 days to show you won’t be threatened, right?

Instead of Trump playing another game of “You think you’re crazy, I’ll fucking show you crazy…”
