But it is important to remember the history. A previous generation of these Democrats first insisted on shoving their South Vietnamese allies aside, and trying to run the war for them; then of imposing all kinds of restraints on their battlefield commanders which, in aggregate, made victory impossible. And then, when they tired of the war, they abandoned the Vietnamese to their fate, with the additional Congressional touch of cutting off South Vietnam’s supply of arms and ammunition. Finally, they just watched as the Communist guerrillas from the jungle were replaced by North Vietnamese regulars in tanks, driving openly down the American-built highways to receive the surrender of Saigon, while the U.S. Seventh Fleet was hovering offshore, with the equipment to "mow them down to marmalade."
It was a rout so ignominious, that it destroyed the credibility of the United States, probably adding ten years to the life of the Soviet Empire.
