U.S. President Donald Trump says he ordered two nuclear submarines to be positioned in the "appropriate regions" as a response to comments made by Russia's former president. CBS News' Charlie D'Agata reports.

Washington

President Trump announced on social media that two nuclear submarines are being positioned in response to remarks by former Russian President Dmitry Medvedev. Medvedev had criticized Trump's ultimatums regarding Russia's actions in Ukraine, calling them threats and steps toward war.

The U.S. Navy declined to comment on the specifics of submarine movements, citing standard policy not to disclose such information. There was no confirmation whether the submarines in question are nuclear-armed or nuclear-powered, and it remains unclear if the announcement reflects an actual change in military posture or is intended as a message amid escalating rhetoric between U.S. and Russian officials.

Trump says nuclear submarines moved in response to Russia

All right, now to a dramatic escalation between the U.S. and Russia. President Trump has taken to Truth Social, saying he is sending, quote, two nuclear submarines to be positioned in the appropriate regions, just in case these foolish and inflammatory statements are more than just that. Now, the declaration is in response to former Russian President Dmitry Medvedev's comments, saying that each new ultimatum that Trump makes toward Russia in pressuring an end to the nation's conflict with Ukraine is a threat, I should say, and a step towards war. Joining us now from the Pentagon is CBS News senior national security correspondent Charlie Nageda. Charlie, good to have you on, my friend. What more are we learning? Do we know where these subs are headed? Tom, you know, I just came back from Navy, and I got the answer that I was kind of expecting, which is no comment. And there's a reason for that, is because the Navy never divulges the location of their submarines, unless they are tasked to do it, in order to send a message. Now, in terms of positioning, there are always a few nuclear-capable submarines on patrol, but they don't have to be on patrol to pose a threat to Russia, because, in terms of the nuclear-armed submarines—and there are two different categories there—they can pretty much hit Russian targets from almost anywhere. So there are also generally two nuclear-powered submarines that carry 100 conventionally-armed cruise missiles, and they are patrolling the Atlantic and the Pacific. It might be that the president is talking about those, in which case he could get those closer to Russian targets. But, again, it was very vague, in terms of—when he says nuclear submarines, there are nuclear-armed submarines and nuclear-powered submarines, but not always nuclear-powered—nuclear-armed submarines. And, Charlie, just walk us through this. How did we get to this point? Yeah, well, it all started Monday, when, as you said, Russian president—former Russian president Dmitry Medvedev, he started complaining about Trump's decision to give Russian President Vladimir Putin 10 days to change his course in Ukraine or risk, you know, more ultimatums. And he said, each new ultimatum is a threat and a step towards war. He posted that on X. Trump then warned Medvedev, who he called the failed former president of Russia, who still thinks he's the president, to watch his words—he's going into very dangerous territory. Well, Medvedev then suggested that Trump should watch the apocalyptic movie The Walking Dead and referred to the Soviet Union's last—launching a last-ditch automatic nuclear strike. And it said Russia is right about everything and will continue to go its own way. So, after that is when President Trump made this announcement. So, you know, you just mentioned escalation. Before we got into this conversation, it's certainly an escalation in terms of the war of words. But in practical terms, where America's submarine fleet is located or where it's moving, we may get a message later from Navy or from STRATCOM. If it is indeed a decision that was made by the president, again, they will only divulge that sort of information if they are directed to do so. Yeah, a war of words involving The Walking Dead. Not exactly on my 2025 bingo card. Charlie D'Agata, we appreciate it. We know you'll stay on top of it. Thank you.
