Japan didn’t have sights on U.S.

By November 4, 2010


Mr. George Alger’s recent letter provided historical information leading up to the Japanese attack on Pearl Harbor on Dec. 7, 1941. His thesis was that the Japanese never had any intentions of invading the U.S. mainland after the surprise attack on Pearl Harbor. Mr. Alger concluded by hoping his letter “stimulates readers.”

This letter provides additional information that supports his thesis on the Japanese intentions after the Pearl Harbor attack.

The Japanese War Plan, as of 6 September 1941 was:

1) Destruction of the U.S. Pacific Fleet and British/American air forces on the Malayan Peninsula and Luzon.

2) While British/American navies were decimated and disorganized, a quick conquest of the Philippines, Guam, Wake, Hong Kong, Borneo, British Malaya (w/Singapore) and Sumatra.

3) Once the above are secure, then Java and the rest of the Dutch Islands would be mopped up.

4) An intensive development of Malayan and Indonesian resources in oil, rubber, etc.

5) Establishment of a defensive perimeter running from the Kurile Islands though Wake, the Marshalls, around the southern and western edges of the Malayan Barrier to the Burmese/India border.

6) With these bases, Japan could cut the lines of communication between Australia and New Zealand and the U.S. and Britain.

7) Then Japan would proceed to completely subjugate China.

If these phases were successful, over half of the world population would be under the economic, political and military control of Japan.

After the Doolittle raid, Admiral Yamamoto planned to extend the defensive perimeter (Item 5 above) to include Midway Island to 1) prevent further bombing raids on Japan and 2) force an engagement to destroy the remains of the U.S. Pacific Fleet at Pearl. With the U.S. Pacific Fleet wiped out Japan could make her defensive perimeter impregnable and could organize her conquests (Items 2, 3 and 4.)

A large body of World War II historical information/books has been published. But nowhere can it be found that the Japanese had plans to invade the U.S. mainland. The Japanese Sept, 6, 1941, War Plan clearly does not involve the U.S. mainland. Thus Mr. Longhofer’s assumption in his Nov. 3 letter is dead wrong. The second paragraph is pure personal conjecture, e.g., “Hawaii would have been next, giving Japan a perfect staging area for future operations against our West Coast.” In Europe it was the British (with an assist by Polish cryptanalysts) who broke the German Enigma code.

The last paragraph is conjecture; for example, it ignores the German Wehrmacht finally running up against a stone wall and being defeated by the Russian army. One might also conjecture what would have happened if the German Wehrmacht had defeated the Russian Army as originally planned? Would codes have mattered?

Mr. Alger’s letter provided an analysis that correctly concluded the Japanese had no intention invading the U.S. mainland.
