What the heck are you talking about? Saying a computer prevented the Nazi government from controlling the world? Are you crazy? A computer didn't do jack, except crack a few codes. If you think codes are the key to success, then you're saddly mistaken.
Man power is the key to success, not codes. Yes, codes allow peopel to communicate to each other, but that doesn't dictate what happens on the ground. Such as tanks, infantry, machine guns, grenades. Codes can't tell you how a battle is going to happen! Sure, you can say, "beep beep beep" which could mean, "Artillery over here!" But that doesn't mean you win the battle! Man power, and strategy win a battle, not a code.
Computers didn't do jack in WWII. The coalition of American, British, and Canadian forces on D-Day is what what happened in WWII. Not a computer. Pffft...
