Ageed, it was a sad day as America quit too soon in helping the South Vietnamese. There may have been a few Reublicans who cut and ran but it was the majority of the Democrat party that failed to support the South from holding on. The left continues today as well, with their anti-war stance on Iraq, all the while claiming they support the troops. They don't and never have.
IF the US leaves Iraq too soon, the Democrats will brag over their defeat of Republicans and it would mean another fifty years of disinformation on Iraq, and failure in US foreign policy.
