In a bold and alarming declaration, former US President Donald Trump said the United States is deploying nuclear submarines in direct response to a series of provocative remarks made by Russian Security Council Deputy Chairman Dmitry Medvedev. The development has heightened fears of renewed nuclear tensions between two of the world’s most heavily armed nations.

Trump, while addressing a press briefing during a campaign rally, stated that Russia’s recent verbal aggression could not go unanswered and that the US military has already begun strategic positioning of nuclear-powered submarines in key regions across the globe.

"They threaten us. They talk like lunatics. So we are responding like a strong nation should—by positioning our submarines where they need to be," said Trump.

This statement comes amid increasingly hostile rhetoric exchanged between Trump and Medvedev, whose recent comments included open speculation about a future nuclear standoff with the United States.

Background of the Verbal Clash

Over the past week, Medvedev made a series of statements suggesting that the US and its allies should be prepared for military consequences if they continue to "interfere in Russian affairs" or push NATO activities closer to Russian borders. Medvedev, a close ally of President Vladimir Putin, also insinuated that nuclear retaliation is always an option if Russian sovereignty is threatened.

In response, Trump fired back, calling Medvedev a "reckless puppet" and accusing him of issuing "irresponsible threats against global peace." Trump, who is currently contesting the 2026 presidential elections, has made national security a central theme of his campaign.

He added, "We're not going to sit back and watch Russia make threats. We've taken action. Nuclear submarines are already on the move."

What does the submarine deployment imply?

The deployment of US nuclear submarines, especially in international waters near Russia or its allies, is viewed as a major military escalation. These submarines are capable of launching intercontinental ballistic missiles (ICBMs) with nuclear warheads and are considered one of the most powerful deterrents in modern warfare.

Strategic deterrence through submarine movement is a long-standing US policy, but rarely is it announced with such political bravado, especially by a former president. Military analysts warn that such declarations—especially if they are verified through satellite tracking or maritime activity—can increase tension, potentially prompting retaliatory moves from the Russian Navy.

A retired US naval commander commented, “If Trump’s claims are true and actual deployment has begun, it suggests an alarming breakdown in the diplomatic backchannels that typically prevent these escalations.”

Biden administration’s silence and implications

Interestingly, the current Biden administration has not commented on Trump’s claims. The Pentagon and State Department both declined to confirm or deny any active deployment of nuclear submarines in response to Russia's rhetoric.

This raises questions about whether Trump is revealing classified information, exaggerating his influence, or perhaps preempting official policy to shape public opinion ahead of the 2026 elections.

White House insiders, speaking on the condition of anonymity, said that President Biden is being briefed on all developments, and US intelligence agencies are closely monitoring Russian military movements.

Russia’s reaction to Trump’s announcement

In Moscow, Medvedev’s office dismissed Trump’s statement as “sabre-rattling and political theatre.” However, Kremlin spokespersons did not rule out a military response, particularly if US submarines are detected near Russian waters.

"This is exactly the kind of escalation we warned about. The American military-industrial complex continues to play with fire," said a Russian official in a televised statement.

Russian state media has already begun circulating reports warning citizens about increased Western hostility and urging national unity in the face of "aggressive posturing."

Global reactions and concerns

Global leaders and defense analysts have responded with concern. The United Nations Security Council is expected to convene an emergency session to discuss rising nuclear tensions. NATO allies, especially in Europe, are reportedly in close contact with US military leaders to assess any strategic shifts.

China, often seen as an observer in US-Russia conflicts, urged both nations to exercise restraint. In a statement, the Chinese foreign ministry said, “The international community cannot afford another Cold War-style conflict.”

Germany, France, and Japan have also issued statements emphasizing the need for diplomatic engagement and transparent dialogue.

Domestic impact on Trump’s election campaign

Trump’s announcement appears to have energised his base, with supporters hailing him as the only leader who can stand up to global threats. National security has become a central issue for Republican voters, and Trump is using the Russia narrative to frame himself as strong on defence.

Critics, however, argue that unofficially declaring military deployments and engaging in public taunts with foreign leaders can dangerously undermine US foreign policy coherence.

A former CIA officer commented, “This isn’t just campaign talk. If foreign powers believe it’s real, it can have actual consequences. And that’s a risk.”

Conclusion

The statement made by Donald Trump regarding the deployment of US nuclear submarines in response to Russian provocations marks a significant escalation in geopolitical rhetoric. Whether this move is symbolic or real, its impact on global security discourse is undeniable.

As the world watches for signs of further escalation or de-escalation, one thing is clear: US-Russia relations remain deeply fragile, and the nuclear threat, once considered a relic of the Cold War, has again taken centre stage.
