I'll give you one thing; you are certainly well thought. The one thing you are missing is that Japan attacked Pearl Harbor to sink the Aircraft carriers. The American Carriers are key to Japan holding any real estate in the Pacific.

As soon as the Japanese even looked like they would try to occupy Hawaii, for even a short period, every US Naval resource would have been allocated to the defense of the Islands.

You propose that Japan occupies Hawaii for a short time ans uses it as a bargaining chip..........wouldn't happen.

Guam, Midway and Luzon would not wither on the vine they would be supplied through the Phillipines, Singapore and Australia. Japan could not hold Singapore without controlling the Phillipines.
