McCain: I Do Believe Trump Would Send in Forces If Russia Invaded a NATO Ally

SCIUTTO: “Senator McCain, do you have any doubt that if Vladimir Putin were to invade a NATO ally, for instance, Estonia, do you believe that President Trump would send U.S. forces to defend them?” 
McCAIN: “I do believe that. And I believe that President-elect will understand better over time the need for an American presence here. And he himself has said we need to rebuild the military which has been harmed dramatically over the last eight years.”
