President Roosevelt was warned about Pearl Harbor

A new book reports that two days before the Japanese attack on Pearl Harbor that officially brought the United States into World War II, President Roosevelt was warned about such a possible attack in a memo from naval intelligence.

U.S. News' Paul Bedard writes more about the story:

In the newly revealed 20-page memo from FDR's declassified FBI file, the Office of Naval Intelligence on December 4 warned, "In anticipation of open conflict with this country, Japan is vigorously utilizing every available agency to secure military, naval and commercial information, paying particular attention to the West Coast, the Panama Canal and the Territory of Hawaii."

The memo comes from Craig Shirley's new book, December 1941: 31 Days that Changed America and Saved the World, which also reports that the Japanese were building a network of spies through their U.S. embassies and consulates. However, Shirley doesn't blame FDR for failing to act on the memo; instead, he compares the Roosevelt administration's inaction to the executive branch's failure to act on pre-9/11 intelligence. In each instance, Shirley contends, the evidence suggests "that there were more pieces to the puzzle" that the White House missed in the days and weeks leading up to the attack. "So many mistakes through so many levels of Washington," said Shirley. "Some things never change."
