Don't get me started :-)
Nixon was a Democrat? Who knew?
“The war had been won.”
Not exactly. Nixon and Kissinger had negotiated a “peace agreement” that left NVA troops still in place in South Vietnam. We didn’t reduce their military to rubble like we did Germany and Japan. This was just another cease fire like we have in Korea and it depended upon a constant US presence to enforce it.
It we had won the war it wouldn’t have mattered if we had left because the North wouldn’t have been in a position to send thousands of armored vehicles into South Vietnam whenever they chose to do so.
