We were killing VC and that was not OK, but it WAS ok for the VC to move south and kill Vietnamese, once we were gone.... Oh sure... not of peep out of the anti-war types THEN.
Also, the Vietnamese sat still for the most pervasive and destructive bombing the world had ever seen... BECAUSE they knew in the end they'd be free.
Once we left... they were SO afraid and ran south in the tens of thousands to FLEE the Communists. They went out into the China Sea in dangerous, unseaworthy boats that were death rather than stay in their homes waiting for the VC.
THAT they would NOT sit still for! Tell you anything?
