President Donald Trump said Friday he had ordered U.S. nuclear submarines to reposition following online threats made by former Russian President Dmitri Medvedev. While the Pentagon has not confirmed the move, the statement marks a rare and pointed nuclear reference amid growing tensions between Washington and Moscow over the war in Ukraine.
Trump made the announcement on his social media platform, framing the move as a precautionary response to rhetoric he deemed reckless. Medvedev, now serving as deputy chairman of Russia’s Security Council, posted a message invoking Cold War-era nuclear retaliation mechanisms and referenced imagery from apocalyptic fiction. Trump, interpreting the remarks as more than rhetorical, stated he took steps to deter further escalation.
It remains unclear whether any U.S. submarines were actually redeployed. Movements of the nuclear fleet are highly classified, and the military typically avoids public comment on such matters. The Pentagon declined to confirm or deny Trump’s claim, referring inquiries to the White House.
Trump’s message represents the first time during his current term that he has publicly tied U.S. nuclear assets to the ongoing conflict in Ukraine. Though he has steadily shifted toward a more adversarial posture on Russia in recent months, he had previously refrained from invoking the nuclear arsenal.
Earlier this week, Trump advanced a series of measures aimed at increasing pressure on the Kremlin. He shortened a previously announced 50-day deadline for Russia to enter peace negotiations with Ukraine to roughly ten days. He also pledged to impose secondary sanctions on countries that continue to purchase Russian oil, a move likely to impact China, India, and Turkey.
Despite ongoing virtual communication between Trump and Russian President Vladimir Putin, the two have not met in person since Trump took office. Trump has repeatedly indicated that direct talks with Putin are the only way to bring about a resolution in Ukraine. However, his recent actions suggest a harder stance is taking hold.
Medvedev’s recent remarks are consistent with his long-standing role as a belligerent figure in Russian political messaging. Though he no longer holds executive authority, his statements are often seen as aligned with the Kremlin’s strategic communications.
The U.S. has been measured in its responses to Russian nuclear rhetoric since the invasion of Ukraine began. American officials have repeatedly warned against any use of nuclear weapons, but have not publicly announced repositioning or alerting nuclear forces. Trump’s reference to submarine deployment is one of the few instances of direct nuclear posturing by a U.S. president in recent memory.
The nature of the submarines Trump referred to remains unclear. The United States maintains both nuclear-powered attack submarines and nuclear-armed ballistic missile submarines. The latter, designed for stealth and long-range deterrence, typically remain hidden undersea and do not require repositioning to maintain strategic reach. Military analysts note that revealing their movements can compromise operational security.
Trump briefly addressed reporters before departing the White House for the weekend, reiterating his rationale as a matter of national safety. He emphasized that the decision was intended to deter threats and protect American lives.
