What a load of BS. He was there, Dubya wasn't. He stood up for his convictions while Dubya was snorting coke and getting caught DUI. Johnson and Nixon weren't into "nation building", just as Shrub is not into "nation building" today. Look where we ended up - dead US civilians being strung on on bridges. But you were the one insinuating that the Iraqi people would love us once we toppled Saddam right after we found the WMDs.
So whatever happened after the US pulled out of Saigon in 1973 is Kerry's fault? Only in your fantasy world, and in Shrub's religious far right-wing mind. Maybe we should have stayed over there and had tens of thousands more Americans killed to satisfy you.
