In a striking escalation of rhetoric amid ongoing tensions over the Ukraine conflict, President Donald Trump revealed Tuesday that the United States recently dispatched a nuclear submarine to counter what he described as a direct threat from Russia.
Speaking at a campaign-style rally in Pennsylvania, Trump framed the move as a necessary precaution against “foolish and inflammatory” provocations from Moscow, underscoring America’s unmatched military superiority.
“We were a little bit threatened by Russia recently,” Trump told the crowd, his voice rising with characteristic bravado. “And I sent a nuclear submarine—the most lethal weapon ever made. Number one: you can’t detect it. We’re 25 years ahead of Russia and China in submarines. We’re WAY AHEAD of everybody in that.”
The president’s comments, which quickly went viral on social media, appear to reference a heated exchange earlier this year with Dmitry Medvedev, Russia’s former president and current deputy chairman of the Security Council.
In August, Medvedev took to social media X to lambast Trump’s threats of severe sanctions on Russian oil exports unless Moscow agreed to a ceasefire in Ukraine. “Each new ultimatum is a threat and a step towards war,” Medvedev wrote, invoking Russia’s nuclear doctrine in a post that many interpreted as a veiled warning of retaliation.
Trump’s response at the time was swift and public.
On August 1, he posted on Truth Social: “Based on the highly provocative statements of the Former President of Russia, 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.”
Later that day, as he departed the White House for his New Jersey estate, Trump elaborated to reporters: “A threat was made by a former president of Russia, and we’re going to protect our people.”
A Familiar Tactic in Trump’s Playbook
This isn’t the first time Trump has leveraged America’s nuclear triad—the combination of submarines, bombers, and land-based missiles—to project strength. During his first term, he ordered similar submarine deployments near the Korean Peninsula in response to North Korean provocations.
Analysts note that U.S. Ohio-class submarines, which are nuclear-powered and capable of carrying Trident II ballistic missiles armed with nuclear warheads, are a staple of the country’s deterrence strategy. Between eight and ten such vessels are typically at sea at any given time, positioned globally to ensure second-strike capability against adversaries like Russia.
However, Trump’s casual invocation of these assets has raised eyebrows. “This is irresponsible and inadvisable,” said Daryl Kimball, executive director of the Arms Control Association. “No leader should be threatening nuclear war, let alone in a juvenile manner on social media.” Hans Kristensen of the Federation of American Scientists echoed the sentiment, pointing out that while the submarines are always ready, publicizing their movements risks unnecessary escalation.
The Pentagon has remained tight-lipped, adhering to protocol by not confirming specific deployments. A spokesperson for U.S. Strategic Command declined to comment on operational details but reaffirmed that “our nuclear posture remains postured for deterrence and is fully capable of responding to any threat.”
Roots in Ukraine Stalemate
The submarine dispatch ties directly into Trump’s deepening frustration with Russia’s war in Ukraine, now in its fourth year. Earlier this summer, Trump issued a series of deadlines for President Vladimir Putin to halt operations—first 50 days, then 10 to 12, and most recently by August 8—threatening tariffs and sanctions if unmet. Putin, in a rare interview last month, dismissed the ultimatums, insisting on a “lasting and stable peace” but offering no concessions.
Medvedev, often seen as Putin’s online attack dog, has amplified the Kremlin’s hawkish stance. His August posts not only criticized Trump’s “ultimatum game” but also referenced Soviet-era nuclear strike protocols, prompting fears of a return to Cold War-era brinkmanship. Trump’s envoy, Steve Witkoff, was dispatched to Moscow shortly after, but talks yielded little progress.
On Tuesday, Trump didn’t hold back on Putin either, mocking the Russian leader’s appearance and strategy. “I said to him, you know, you don’t look good—you’re four years fighting a war that should have taken a week. Are you a paper tiger?” he quipped, drawing cheers from the audience. He also dismissed Medvedev as “some very stupid person working for Putin.”
Social media erupted with reactions. Posts on X highlighted clips of Trump’s speech, with users debating.
Expert Views: Deterrence or Danger?
Security experts are divided on the implications. At the Center for Strategic and International Studies (CSIS), analysts described the deployment as “probably the least provocative step possible while still making a political and diplomatic statement.” Unlike raising nuclear alert levels or forward-deploying bombers, repositioning submarines—already a routine part of U.S. operations—sends a message without immediate risk.
Yet others warn of the cumulative effect. “Russia’s rhetoric, save for Medvedev, has been muted so far,” a CSIS report noted in September. “But more threatening language could engender another U.S. response.” With both nations holding the world’s largest nuclear arsenals, even perceived slights can spiral.
The White House insists the action was purely precautionary. “Words are very important, and can often lead to unintended consequences,” Trump wrote in his initial post. “I hope this will not be one of those instances.”
As Trump barrels toward the 2026 midterms, his unfiltered approach to foreign policy continues to polarize. For now, the submarine—lurking silently beneath the waves—serves as a stark reminder: In the game of nuclear chicken, deterrence is as much about perception as power.
