On Korea, MacArthur was right

An article on the Korean War conflict between General MacArthur & President Truman. The article pointed out that General MacArthur was ultimately right in his quest to destroy the Yalu River bridges & prevent China's incursion into the Korean Peninsula during the 1950-1953 Korean War. The War was practically over, and the North Koreans were essentially vanquished, when nearly the entire Chinese Red Army pushed southward into North Korea to backstop the N. Korean regime. The result over 33,000 Americans died in the Korean conflict in the UN-sponsored battle over Korea. The article surmises the question: What would have been the result if General MacArthur had undertaken his plan to blow up the Yalu River bridges?
