RUSSIA has dismissed Donald Trump’s warning he is sending nuclear submarines closer to Russia as a “temper tantrum”.

While the Kremlin has yet to respond, the US President has been mocked by local media.

Former major general Leonid Ivlev said it did not pose a new threat as the location of US naval forces is known and the range of submarines can be found online.

Another retired lieutenant general called it “meaningless blather”.

And a Russian security expert told one paper: “I’m sure Trump didn’t really give any orders”.

Trump had said he was ordering submarines to “appropriate regions” after ex-Russian President Dmitry Medvedev said they still had Soviet-era nuke capabilities.

He said: “Words are very important and can often lead to unintended consequences.”

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

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 been 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.”

“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!”
