Although I was just a little kid when the Korean War took place, I feel more of a kinship to the events of this era than the Viet Nam War, which was my generation's benchmark.
My dad took the family to Japan for a decade while he was employed by the Army and State Department in direct support of our forces in Korea by way of Japan. I got to travel to Korea a half dozen times in the 1950s--it was only slightly more primitive and bombed out than Japan was in the late 1940s. It has been my impression that the South Koreans really wanted to be free of Communism and would fight for rights Americans took for granted. The Viet Namese didn't.
The Viet Namese didn't I know several Vietnames refugees who would disaggree with that statment. Much the same was said of the ROK forces during the Korean war as was said of the ARVN forces during Vietnam. The ARVN, with some help from US air power, fought off a combined arms assault by the NVA, after most US troops had been withdrawn. Then the US Congress cut off their ammunition, spare parts and other logistics support, and the NVA were successfull in their next assault, which was also a combined arms assualt, with tanks, self propelled artillery and so forth.
