NSA report debunks theory that U.S. heard coded warning about Pearl Harbor
Specifically, who heard or saw a transcript of a Tokyo shortwave radio news broadcast that was interrupted by a prearranged coded weather report? The weather bulletin signaled Japanese diplomats around the world to destroy confidential documents and codes because war with the United States, the Soviet Union or Britain was beginning.
In testimony for government inquiries, witnesses said that the “winds execute” message was intercepted as early as Dec. 4, three days before the attack.
But after analyzing American and foreign intelligence sources and decrypted cables, historians for the National Security Agency concluded in a documentary history released last week that whatever other warnings reached Washington about the attack, the “winds execute” message was not one of them.
A Japanese message intercepted and decoded on Nov. 19, 1941, at an American monitoring station on Bainbridge Island, in Washington State, appeared to lay out the “winds execute” situation. If diplomatic relations were “in danger” with one of three countries, a coded phrase would be repeated as a special weather bulletin twice in the middle and twice at the end of the daily Japanese-language news broadcast.
“East wind rain” would mean the United States; “north wind cloudy,” the Soviet Union; and “west wind clear,” Britain.
In the history, “West Wind Clear,” published by the agency’s Center for Cryptologic History, the authors, Robert J. Hanyok and the late David Mowry, attribute accounts of the message being broadcast to the flawed or fabricated memory of some witnesses, perhaps to deflect culpability from other officials for the United States’ insufficient readiness for war.
