Questions from Sarah 2 - War in the Pacific

From Sarah:

also, would you say the main reasons for the japanese defeat were :

rapid rate of japanese conquering territories - inability to consolidate new territory, men and resources spread all over pacific,
j. without a clear plan
inability to produce enough aircraft, shipping etc- could barely cope with losses, whereas america's manufacturing ability gave america the advantage.
also, japan suffering from shortages in materials and food.
division within j. leadership

All of these are good +

I would also add: Magic - let the allies know exactly what Japanese were going to do before they did it.

& allied submarine warfare - sank so much Japanese shipping it wasn't funny - they got almost nothing back to Japan.

THEY SHOULD HAVE DESTROYED THE SUBMARINE PENS WHEN THEY HIT PEARL H.
