The China intervention was a screw up by Almond dispersing X Corp.
And as the General on the ground he was telling MacArthur in Tokyo not to worry about the Chinese.
So Mac gets credit for all success, and blame for failure goes to subordinates? Compare that to Ike who was prepared to take the failure of D-Day entirely on himself. Maybe he should have left Tokyo and seen for himself. But what he was hearing coincided with his own bias. He foolishly held the ability of the Chinese soldier in contempt.
