Sorry, but I don't see anything new here.

It has always been accepted that:

1. The US knew the Japanese were going to attack us. Most of the top commanders believed the attack was going to be in the south, few seriously believed the attack would be in Pearl Harbor. It's well known that a few stratigists believed PH could be the target, but it's equally well known that they were in a minority. The Navy was still dominated by "gun club" commanders. They firmly believed that the US Navy could not pull off a major attack 5,000 miles from base, and they also were convinced that the Japanese were inferior to us.

2. The intellegence received from the broken Japanese naval code was mishandled by commanders in Washington. The conspiracy nuts always want to paint this as intentional, but there just isn't any evidence to believe that it wasn't anything but incompetence, in many cases due to the naval doctrines mentioned in 1.

3. FDR was resigned to the fact that we were going to war with the Japananese sooner or later, in At Dawn We Slept it was pointed out that he was overheard saying something to the effect that if he had known the Japanese were going to beat us so badly he would have babied them along a little longer. Now it would be reasonable to conclude that this showed he knew the Japanese were going to attack us in advance, and that he was pushing them to attack at that point in time, but I don't think you can necessarily conclude that it meant he knew we were going to be attacked at PH, or that he was forcing Japan's hand in going to war with the US.

Japan sealed it's own fate. War between the US and Japan was initiated completely by Japan. they did it with their eyes fully open. They wanted Asia for Asians an they wanted hegemony over Asia. To say that FDR was responsible for war with Japan is just plain ridiculous.
