Hi Brian & Ruy,
as I mentioned in my post, I would reserve judgement because I haven't read the book. However, I stand by my original statement which is not a criticism of the author or his research; rather the publisher. Read the name of the book carefully (my emphasis by underlining the word):
"Preemptive Strike – The Secret Plan That Would Have Prevented the Attack on Pearl HarborPreemptive Strike – The Secret Plan That Would Have Prevented the Attack on Pearl Harbor"
Cheers from a WWI General (who also has spent over GBP3,000 on original archival documents in the last year)
