Ignoring PLA south of the Yalu was another good one on Mac.
Island hopping and Inchon were brilliant. Overall, still think he was pompous. Nothing to do with leftist sources. For what it’s worth, I’m old enough to have lived in a bygone time when the left had not polluted every aspect of culture and history.
Any ignoring of the PLA buildup on the Yalu was done by the State Department and CIA.
Macarthur was well aware of the PLA buildup. MacArthur's failure was his failure to understand that Truman, the president who turned China red and was responsible for the Korean War by stating Korea was not in the American zone of interest would not treat large scale Chinese intervention on the Korean peninsula as an act of war.
Macarthur believed that no Chinese commander would hazard large scale intervention on the Korean peninsula given the ability of largely unopposed American air power to strike at will their bases of attack and lines of supply both north and south of the Yalu. The risk of utter destruction of Chinese forces on the Korean peninsula through lack of supply would be too great.
Macarthur's failure was not to recognize what was happening along the Yalu but rather his failure to recognize the changed political landscape in a Washington infested with Leftists.
Nothing to do with leftist sources.
I disagree.
