I'd say those were the result of abandoning Chiang Kai-Shek. No Communist China - no Korean or Vietnam War.
I remember Robert L. Scott in his book “Flying Tiger”, mentions that he was told he could not bomb some bridges which the Japanese were using because Mao wanted them intact.
“I’d say those were the result of abandoning Chiang Kai-Shek. No Communist China - no Korean or Vietnam War.”
The treaty ending WWII separated Korea into a Soviet and US spheres; China had nothing to do with that. If anything, we bought Chiang 8 more years from 1937 on. While the fall of China did make it easier for the war in Vietnam to happen, the Soviets provided much of the arms (as well as pilots) to Ho Chi Minh.
