chiang was highly restless when korean war broke out, willing to send troops there, but truman rejected.

if north korea was taken, chiang's confidence was going to further up, he dreamed everyday of comeback

korean war taught all sides big lessons. mao totally gave up of occupying TW, america made the decision of avoiding direct conflict with ccp on land ( a big reason why norht vietnam was never in dnager of losing)

basically all histories ahppend for good reasons, rarely they were avoidable.

korean war was inevitbale, american's involvement was so, and ccp's so.
