How does a military genius get his entire air force destroyed on the ground in the Phillipines 10 hours after Pearl Harbor?
And how does a military genius deliberately ignore multiple reports of Chinese troops in large numbers in Korea?
You used the quote about Patton and then proceeded to talk about what MacArthur did. MacArthur did not like Patton. It seems rather bizarre for you to try damning Patton for the things done by MacArthur.
MacArthur has many errors to answer for in his career, but it should also be recognized and acknowledged that he did much to minimize casualties during WWII. That is one redeeming virtue shared by Patton and MacArthur, they eschewed conentional tactics to overcome the enemy with far fewercasualties than less competent generals and admirals.
It is also little recognized that MacArthur may have been able to win the Philippine Defensive Campaign if Eisenhower had not persuaded the Army to abandon the Philippines. The Japanese offensive in Bataan had failed, causing the transfer of major forces from French Indochina to resume the offensive. These Japanese reinforcements also were failing. With even a modeest reinforcement, food, medicine, and other support, the whole Japanese offensive into Indonesia and the Solomons may have been derailed and those costly counter-offensives have been made unnecessary.
