In just barely under six months after Pearl Harbor, the US Navy trounced the Japanese Navy at Midway, in what was the turning point in the whole Pacific war. There was still a lot of battles to be fought, but from that point on, the Japanese were, for all intents and purposes, on the defense.
Think about it...
From Pearl Harbor to turn around in ONLY 6 MONTHS.
We were lucky kid... the Jap navy kicked our ass most of the time.
One flight commander, McCluskey, found 3 carriers and pay-dirt off Midway.
Think about this... we lost 2000 on Tarawa, 5000 on Iwo and 10,000 on Okinawa.
You have a comic book view of history.
