Have you ever noticed that there have been quite a few WW II movies and books where there is a German agent in the "hero" role ("The Eye of the Needle" for instance), you know they are the enemy, but there is still a sympathetic attachment to them. However, you will never see the Japanese portrayed this way. I fear that in fifty years, September 11th will have lost it's significance the same way December 7th seems to have lost it's.
And, sadly, we'll let our guard down and there will be another Pearl Harbor or 911.
Japan has been a pretty good allie of the USA. It is a highly secular, advanced, "socially progressive" society (yeech), not a shintoist dictatorship. As a matter of fact, it is probably the most nonreligious society outside of Europe.
