President Donald Trump revealed on 3 August that American nuclear submarines have moved into position near Russian waters, confirming the deployment he ordered just days earlier in response to escalating threats from Moscow.

“They are in the region, yeah, where they have to be,” Trump told reporters when asked about the submarine positioning, according to The Hill.

The submarine deployment represents Trump’s most direct military response yet to what he called “highly provocative statements” from Dmitry Medvedev, Russia’s former president who now serves as Deputy Chairman of the Security Council.

What triggered the submarine deployment

The military positioning follows Trump’s 10-day ultimatum to Russia over the Ukraine war. Trump threatened tariffs and sanctions unless Moscow shows progress ending the war.

Medvedev fired back, accusing Trump of “playing a game of ultimatums with Russia.” The Russian official warned that “every new ultimatum is a threat and a step toward war” – targeting not Ukraine, but Trump’s “own country.”

On 31 July, Trump told Medvedev to “watch his words” and calling him a “failed former President of Russia, who thinks he’s still President.”

“He’s entering very dangerous territory!” Trump declared, noting that “Russia and the USA do almost no business together. Let’s keep it that way.”

Medvedev responded by invoking Russia’s “Dead Hand” nuclear system and telling Trump to “remember his favorite zombie movies.”

On 1 August, Trump announced his submarine deployment on Truth Social: “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.”

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

Kremlin spokesman Dmitry Peskov downplayed the submarine news, telling Russian media that “American submarines are already on combat duty anyway. This is a constant process.”

But Peskov stressed Russia’s careful approach to nuclear rhetoric: “We are very careful about any statements related to nuclear issues. Russia takes a responsible position.”

When pressed about Medvedev’s inflammatory statements, Peskov deflected: “In every country, members of the country’s leadership have different views.” He emphasized that “President Putin” formulates Russia’s foreign policy.

What happens next

Trump confirmed his special envoy Steve Witkoff will travel to Russia this week – either 6 or 7 August for talks ahead of planned new sanctions.

The diplomatic mission comes as nuclear-armed submarines patrol near Russian waters, creating a complex backdrop of military pressure and negotiation attempts.
