Arguing about how weak or worn out America’s military is pointless. Ditto for America not being able to lead a NATO military response. At no point during the Cold War did either America or NATO get involved in a direct military confrontation with the Soviet Union. Not over missiles in Cuba, the Berlin wall or the invasion of Afghanistan. So why would any sane person expect that to happen now? There will be painful payback in the form of economic sanctions. Anyone willing to entertain the notion of an all out military reaction by the U.S. or NATO, however, completely lacks historical perspective.
