A Vladimir Putin ally has delivered a grave warning to Americans: vote for Donald Trump or prepare for a nuclear war.

Vladimir Zhirinovsky told Reuters that if Hillary Clinton is elected as the next U.S. president, it would set off “Hiroshimas and Nagasakis everywhere.”

“Relations between Russia and the United States can’t get any worse,” the leader of the country’s nationalist Liberal Democratic Party told the news agency during an interview in Moscow. “Americans voting for a president on Nov. 8 must realize that they are voting for peace on planet Earth if they vote for Trump. But if they vote for Hillary it’s war. It will be a short movie.”

Zhirinovsky is notorious, like Trump, for his unfiltered chatter and has praised the presidential nominee in the past for his admiration of Putin.

He also dropped a Clinton bombshell, saying she is not fit for the presidency since she’s a woman.

“Most Americans should choose Trump because men have been leading for millions of years,” he said. “You can’t take the risk of having one of the richest, most powerful countries led by a women president ... If Hillary Clinton wins it will be the last U.S. president ever.”
