Yeah, okay, I'll marry him.
sorry to be nit-picky, but that isn't Bush's hand. its the guy with glasses, to the left of Bush. Bush's hand is in the scrum, but its down lower grabbing a hold of his SS agent.
Have you looked at this photo uncropped? Note the gun on the hip of the Chilean in front (both arms apparently engaged holding back an American agent). The President a few feet away, at top right.

As another poster wrote, "I can't think of another instance in modern history that a President personally went against armed foreign nationals."
Best photo so far of the Chile incident.
