President Donald Trump announced Friday that he has “ordered two Nuclear Submarines to be positioned in the appropriate regions” following “highly provocative statements” made by former Russian President Dmitry Medvedev.

Medvedev said earlier this week that Trump’s new deadline for Russia to end the conflict with Ukraine is an additional “step towards war.”

“Based on the highly provocative statements of the Former President of Russia, Dmitry Medvedev, who is now the Deputy Chairman of the Security Council of the Russian Federation, 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 post on Truth Social.

“Words are very important, and can often lead to unintended consequences, I hope this will not be one of those instances,” he added.

There was no immediate response to Trump’s comments from Russia. The Russian Foreign Ministry did not immediately respond Friday to a request for comment from Fox News Digital.

Medvedev, now the deputy chairman of the Security Council of Russia, cautioned that Trump’s announcement Monday that Russia must end the conflict with Ukraine in 10 to 12 days would not end well for the U.S.

“Trump’s playing the ultimatum game with Russia: 50 days or 10… He should remember 2 things: 1. Russia isn’t Israel or even Iran. 2. Each new ultimatum is a threat and a step towards war. Not between Russia and Ukraine, but with his own country,” Medvedev said in a post on X on Monday. “Don’t go down the Sleepy Joe road!”

While Trump announced on July 14 that he would sign off on “severe tariffs” against Russia if Moscow failed to agree to a peace deal within 50 days, Trump said Monday that waiting that period of time was futile amid stalled negotiations.

“I’m going to make a new deadline, of about 10 — 10 or 12 days from today,” Trump told reporters from Scotland. “There’s no reason for waiting. It was 50 days. I wanted to be generous, but we just don’t see any progress being made.”

Trump’s remarks come as his frustration with Putin has grown in recent weeks amid no progress toward peace between Russia and Ukraine, and just a day after Russia launched more than 300 drones, four cruise missiles and three ballistic missiles into Ukraine, according to the Ukrainian air force.

Trump also wrote on Truth Social Friday that “I have just been informed that almost 20,000 Russian soldiers died this month in the ridiculous War with Ukraine.

“Russia has lost 112,500 soldiers since the beginning of the year. That is a lot of unnecessary DEATH! Ukraine, however, has also suffered greatly. They have lost approximately 8,000 soldiers since January 1, 2025, and that number does not include their missing,” the president added. “Ukraine has also lost civilians, but in smaller numbers, as Russian rockets crash into Kyiv, and other Ukrainian locales. This is a War that should have never happened — This is Biden’s War, not ‘TRUMP’s.’ I’m just here to see if I can stop it!”
