renmin said:That is very true, my opinion:I believe Mc Arthur wanted to attack mainland China for revenge after his stagering defeat, obviously, trumen disagreed with this not because this will spark a world war but the US is too far away and there really no efficient way to attack the PRC without being nailed, BUT, if the US and Sk had won, then I garantee you that the US would have built an military base and raid an envasion for mainland China.
Yes, McArthur wanted to nuke China. But Truman did not want another WW and fired him.
if china had chosen to continue the plan on attacking taiwan, then there can be two outcomes: 1) taiwan would be taken back and there wouldn't be and crisis in the taiwan strait today, of course north korea might not exist either and US would have a military base right on the boarder. or 2) PLAN fails to sail across the strait completely and get totally destroyed by the ROC navy, as well as a US military base just outside the door. out of these two outcomes, the second one is more likely to happen since the PLAN didn't have that many ships and all their ships are crap compared to the ROC navy. plus Mao didn't have much experience in naval battles. (the strait is far more dangerous for PLAN than the Yangzi River).
Mao asked Stalin's help for attacking Taiwan. But it was believed Stalin thought Korea was more urgent. And second, Stalin did not want a China that was friendly to the US. Even a China that was indifference to the US would mean uncertainty for USSR. The USSR and US were at the beginning of the Cold War. China would served as another pawn and counter balance to the US dominant. But Inevitably, China played well into USSR's plan. Also because of US was at the door step and the worried of US sentiment about communism at that time.
USSR was not willing to share its nuclear and other technologies w/ China and not providing assitance for unification of Taiwan. China's relationship w/USSR had gone sour after the Korean War.
