Anyone who wants to defend the traditional myth that FDR and other senior officials had no idea that Pearl Harbor was about to be attacked needs to deal with Dr. Brian Villa and Dr. Timothy Wilford's 36-page monograph in the prestigious journal
Intelligence and National Security (August 2006) (
LINK).
Villa and Wilford dismantle every major argument put forth by the dean of the no-advance-knowledge advocates, Phil Jacobsen.
Jacobsen died the same month the Villa-Wilford article was published, so he can be excused for not responding to it, but not a single one of his disciples has responded to it either.
If you haven't read Villa and Wilford's article, you are posting without the benefit of a huge body of facts on the subject.
