MILFORD, New Hampshire — Donald Trump told an enthusiastic crowd of 5,000 at the Hampshire Hills Athletic Club Tuesday night that “we’ll beat the sh** out of them,” if he is president and the United States is attacked by somebody.

“If we are attacked, somebody attacks us, wouldn’t you rather have Trump as president if we’re attacked?” he asked the crowd.

“We’ll beat the sh** out of them. Anybody attacks us,” Trump said.

Trump suggested that he would like to develop alliances with other countries, Russia in particular, interested in accomplishing that same objective.

“Speaking of potential—because he hates Obama so much—Putin, he said, ‘Donald Trump is a genius and he’s the real leader over in that country.'”

“And these people I’m negotiating with all the time, these people on the stage with me, they say, ‘You should disavow what Putin of Russia said.'”

“I said, ‘I’m not disavowing that he called me a genius,'” Trump said.

“Are you crazy?” he asked.

“Don’t worry,” Trump reassured the crowd. “I can’t be seduced.”

“But, wouldn’t be nice, if you think about it, if we actually got along with Russia and others, and we can use them to knock out ISIS with us?” Trump asked again.

We could work with Russia “so that maybe we don’t always have to pay for it. Knock the hell out of them [ISIS], but let them [the Russians and other potential allies] drop some of their bombs that cost a million dollars apiece. Let them use some of their weapons that cost billions and billions of dollars,” he said.

“Let them beat the sh** out of ISIS also,” Trump suggested.

Trump, who finished second in the Iowa caucuses Monday night, leads his nearest rival in most polls in New Hampshire by 20 points. The Granite’s States first-in-the-nation primary will be held next Tuesday, February 9.

Earlier in the evening, Trump was endorsed by former Sen. Scott Brown, who introduced Trump to the crowd.

Best-selling author Ann Coulter also spoke at the event in support of Trump.
