But as far as I know, we may have half of our population dead with lack of health insurance, natural disasters worsened by AGW, an increasing economic catastrophe before we can see real progress in isolationism/non-interventionism.
I'm afraid you have it backwards. A president can order troops home. Might piss off a few congressmen and lobbyists but that's his call. For the White House to close half of our 1,000 bases around the world is entirely feasible. Ditto with withdrawing from AfPak. On the other hand, laws needed for climate change and health care are in the hands of Congress -- a much tougher nut to crack.
