Respectively disagree that Japan felt it had no choice. Japan wanted war. It had assigned itself the role of leader of Asia. Asians felt humiliated by the dominance of European powers and the United States in their countries. (France Indochina, Netherlands Indonesia, Britain Hong Kong, Singapore, Malaysia and India, United States Philippines and interference in China, even Portugal in China) Japan after its victory over Russia in 1905 and role in WW I viewed itself as the nation that would assume the historic burden of ridding Asia of these demeaning interlopers. It is the motivation that is not appreciated or understood by most Westerners. However it should be understood. Today China assumes that role. It absolutely abhors American involvement in Asian affairs whether it be in Korea, Vietnam, or anywhere in Asia.
An affinity for taking the dominant role by limited wars in asia and being prodded with a sharp pointed stick to do so are vastly different instances.
As the treachery of Harry Dexter White was not more than a suspicion, archival records that prove it and outline it give us an entirely different concept of the outbreak of war or the inevitability of the war in the Pacific.
