Some people hold up MacArthur as some kind of hero. I am not one of them.
I do not deny that he had talent. I do believe he was blinded by his own ego, hobbled by his arrogance, and was never held to account for the mistakes or poor decisions he made in the same way he held others to account.
There were many times he was called to stand in judgement of his fellow officers and the men who served under them and him, and he was merciless.
Had he been held to the same standard, even just once, for what happened at Clark Field, then it would be a different story. But FDR decided we needed a hero, interesting considering their relationship through the rest of WWII.
