DONALD Trump has said that the US is “totally prepared” for a nuclear war following a slew of threats against America from a Kremlin comrade.

In an extraordinary escalation, the commander-in-chief ordered that two nuclear submarines be positioned near Russia 

The nuclear sabre-rattling comes after Dmitry Medvedev, the deputy chairman of Russia’s security council, made an ominous threat and warned that the US is taking drastic steps towards war with Moscow.

Trump slammed Medvedev’s words as “foolish and inflammatory” before ordering the placement of nuclear submarines near Russian territory.

“Based on the highly provocative statements of the Former President of Russia, Dmitry Medvedev, who is now the Deputy Chairman of the Security Council of the Russian Federation, I have ordered two Nuclear Submarines to be positioned in the appropriate regions,” Trump wrote on Truth Social.

Medvedev, who was the former Russian president from 2008 to 2012, seemed to threaten America with nuclear annihilation in the tit-for-tat row with Trump.

He said: “If some words of the former Russian president [Medvedev] cause such a nervous reaction in the entire, formidable US president, then Russia is right in everything and will continue to go its own way.

“Let him remember his favorite films about the “walking dead”, as well as how dangerous a “dead hand” that does not exist in nature can be.”

Medvedev may have referring to Moscow’s “Dead Hand” nuclear weapons system, which is designed to launch a doomsday retaliation attack with full nuclear force – even if the Kremlin leadership is wiped out.

He also warned that Russia “isn’t Israel or even Iran.”

“Each new ultimatum is a threat and a step towards war,” the former Russian president wrote in an X post.

The MAGA prez hit back saying: “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. Thank you for your attention to this matter!”

Trump did not say in his post whether he meant nuclear-powered or nuclear-armed submarines. He also did not elaborate on the exact deployment locations, which are kept secret by the US military.

But in an interview with Newsmax that aired Friday night, Trump said the submarines were “closer to Russia.”

“We always want to be ready. And so I have sent to the region two nuclear submarines,” he said.

“I just want to make sure that his words are only words and nothing more than that.”

Trump’s remarks came hours after Russian President Vladimir Putin said Moscow had started mass producing its hypersonic nuclear-capable Oreshnik missile.

Putin previously said he could deploy them to Belarus, a close Russian ally neighbouring Ukraine, by year-end.

The US has the largest nuclear-powered submarine fleet in the world, including its lead ship the USS Virginia – a 377-feet long sub, equipped with cruise missiles.

The US has nuclear-powered attack submarines that can search for targets.

Several of the US Navy’s vessels are specifically designed for stealth and are able to precisely strike targets with nuclear warheads.

The Western superpower also has larger, nuclear-armed submarines, which do not need to be repositioned as they can reach targets thousands of miles away.

It’s unclear which nuclear submarines will be deployed.

The nuclear sabre-rattling came against the backdrop of a deadline set by Trump for the end of next week for Russia to take steps to end the Ukraine war or face unspecified new sanctions.

Trump initially gave Putin a 50-day deadline to end the conflict before suddenly shortening it to 10 days from July 29 due to a lack of progress on Moscow’s behalf.

The president also vowed to impose secondary tariffs on Russia if it does not reach a ceasefire agreement by August 8.

Despite the pressure from Washington, Russia’s onslaught against its pro-Western neighbour continues to unfold at full bore.

‘TALK DOESN’T MEAN ANYTHING’

Trump has expressed frustration with Putin, questioning whether the Russian leader really wants peace with Ukraine.

In early July, Trump described having a good conversation with Putin over the phone, only to learn the next that Russia had launched another attack on Ukrainian cities.

“I always hang up, [and] say, ‘Well, that was a nice phone call,'” Trump told reporters.

“And then missiles are launched into Kyiv or some other city, and I say, ‘That’s strange.’

“And after that happens three or four times, you say, the talk doesn’t mean anything.”

Trump reiterated that he was “very unhappy” with Putin since their phone call last week made no progress on the Ukraine peace deal – something the US president has pushed for since returning to power.

The savage attack comes as the US president vowed to send more weapons to Ukraine.

But Putin has snubbed peace and is instead steadily increasing his overnight bombing raids – which could soon hit 1,000 a day.

Volodymyr Zelensky, the Ukrainian president, and European leaders have also voiced their concerns that Putin is not interested in peace.

Zelensky said Putin has the final say in any ceasefire with Russia.

“We understand who makes the decisions in Russia and who must end this war,” the Ukrainian president wrote on X.

“The whole world understands this too. The United States has proposed this.

“Ukraine has supported it. What is needed is Russia’s readiness.”
