McNamara was a military analyst who wrote a report on (then) Maj. Gen. Curtis LeMay’s performance with the B-29 while LeMay was in charge of the XX Bomber Command (Kharagpur, India). Big deal!
From what I’ve read, the success of the strategic bombing campaign against Imperial Japan then (and later, when LeMay took charge of the XX Bomber Command) had a lot to do with LeMay and his fine men, and very little to do with “Doctor Strange.”
