President Trump literally put the squeeze on Vladimir Putin during their first meeting on Friday — giving the Russian strongman a bone-crunching handshake as they posed for photos.

“If this shake were a prize fight, and it nearly was, I would have awarded a points victory to Trump,” body-language expert Judi James said afterward.

The 6-foot-3 Trump, she told The Sun, was “dominant” in the grip-and-grin session with the 5-foot-7 Putin.

“The gap [between them] was a sure sign of the pressure felt by both men at that moment, but as Putin raised an almost wary-looking hand for the shake Trump leaned forward with an outstretched arm and offered his hand palm-up,” James said. “This is an infamous power-trap and Putin had no option but to put his hand into the clamp.”

Photos show Trump’s hand wrapped around Putin’s, tightly squeezing the Russian’s fingers.

“Once there he suffered an underarm-patting from Trump that made the US president look like the dominant leader, so much so that Putin responded with a pointed finger, which is the body language equivalent of drawing a weapon,” she said.

The president also looked more relaxed than the former head of the KGB, reputedly a savvy politician and cold-blooded leader.

“If Trump wanted to show friendliness but superior status I have to say he nailed it this time,” James said.
