break the code. :-(

How?

By shutting down their access to oil and other resources.

???

What does that mean? Who is "their"?
Japan's. During the 30's, the Dutch East Indies (IIRC) was the main source
of oil and other resources (Japan had about as many local resources as
they
do now.) They were essentially "shut out".

Ah, you mean the Japanese diplomatic code. There were good retaliatory
reasons we cut off their oil and other resources, but that's neither here
nor there.

I thought maybe you were talking up some secret "revisionist historian
code", or something! :-)
