I've been as down on US foreign adventures since and because of 'Nam as anyone, but to be fair, they thought they were doing a Korea, when they were really doing an Afghanistan. But how could they know? You can't look at Japan or S. Korea and not take some pride in what the US made possible there. You can't look at 'Nam or Afghanistan and not despair, and you can't look at Iraq and Ukraine and not realize the last acts are still yet to written. What I can look back and criticize is that LBJ realized the war was lost and the coward walked away from the presidency instead of ending it, leaving it to Nixon to make it worse. Just as we failed to course correct for way too long in Iraq (Mission Accomplished!) or Afghanistan. I guess I can forgive an American administration trying to do something they think is right, but not one that won't see when a mistake has been made and get out.
