DonS, neither of your points support my counter-thesis. I know you can do better[:D].
The Kennedy Admin. brought about the 1,000 Missile system around 1962-63. By 1967, the program was complete. We had a significant submarine launched capability (all of these compares back then, not the 1970s), and a large number of gravity bombs and a large amount of bombers of all types that were nuclear capable. It's my contention that at this time in History, the US lead the Soviets, significantly.
As for the entry of the Chinese into Korea, after the Inchon Landing, it was just a matter of time before the Chinese were going to enter. I know how everybody likes to say that China needed a buffer state, etc. If that is true, China could've either announced a cessation for a return to the 1945 border, or simply have stopped their drive at the 38th Parrallel instead of continue to drive into Seoul.
What say you?
