nippon didnt even need soldiers to win a battle

http://en.wikipedia.org/wiki/Operation_Cottage

7800 Allies soldiers VS. 0 Japanese soldiers

Japs lose nothing

Allies lose a battleship, 300 are dead, 2500 are wounded

"Their alibi for fighting is to save their face for ancestors waiting in celestial space, we'll kick their precious face down to the other place, we gotta slap a dirty little jap"

So basically the japs were to much of a bitch to actually fight and made us fight each other. The only thing here that beat the allies was themselves.
