Do not think for a moment that Pearl, Wheeler, Hickham and other installations sat vacant prior to that date.Wrong. San Diego was the home port. It moved to Pearl May 1940 as a forward position.
Against the wishes of the Navy.
And while you're at it, tell me where was the U.S. Asiatic fleet based...
The Japanese leadership saw the U.S. as a potential threat to their expansion and drew up plans to neutralize it. As the U.S. started to withdraw trade of raw materials and oil in 1940 and 1941, they were drawn to the conclusion that the U.S. would be a potential adversary and felt that the neutralist American public would not have a stomac for war. Based on that assumption, the Japanese leadership wrongly beleived that a successful attack, or series of successful attacks, on American interests would force the U.S. to the bargaining table.
There were several among the Japanese leadership who disagreed, including Admiral Yamamoto, who even expressed that attacking the United States at Pearl may hold a victory, but would invite disaster for the Empire in the long run.
