Why would they have consulted MacArthur after he was insubordinate and went rogue? Every other general and admiral out there wante dhim drawn and quartered.
When did he go rogue?

Admiral Halsey should have been court-martialed for his 2 screw ups at Leyte.
1) Halsey’s pursuit of the Japanese decoy left the our Leyte invasion force open to attack.
2) On Dec 17, a typhoon destroyed 3 Third Fleet destroyers with 790 sailors and 146 aircraft lost.
Nimitz saved Halsey from being cashiered.
The famous insubordination incident involving MacArthur, which ended with Truman relieving him, was in the Korean War, not WW2. I am not sure if you are referring to an earlier incident or what.
History can be confusing, I know, but VJ Day far predated his going rogue. And LeMay never went rogue.
MacArthur was, as he often was, right on this.
