[ARC5] How the U.S. Cracked Japan's 'Purple Encryption"

[Joe Connor]

Yamamoto recognized from the start that Japan lacked the resources to stand toe-to-toe with the U.S. in a long war. When the U.S. geared up its industrial production, it would overwhelm Japan. Yamamoto realized Japan's only chance was a quick knockout, and that was his plan.
First, he would cripple the Pacific Fleet at Pearl Harbor. He came close but luckily for us, the carriers were at sea, and this was going to be a carrier war, not a battleship war. 
Second, he planned to lure the remnants of the Pacific fleet out to sea, inflict a decisive defeat on the fleet, and force the U.S. to sue for peace. That was Midway. Without the code-break activities, his plan might have worked.

Yes.

But what continues to amaze me is how poorly prepared the Japanese were to carry on and 
support a long-term war with anyone, yet they caused immense grief to many people for 
something like 9 years before being brought to heel.

And Germany never did put its economy on a war-footing the entire war.

Gee... :-(
