Hi, folks!
Interesting points, Upnorth! I remember exactly what you're talking about as far as the portrayals of the Soviets during those years.
Kugai, there is quite a bit of debate over here as well over the circumstances that led to the Pearl Harbor attack, including the very points you brought up.
In my opinion, the lack of knowledge displayed in the pop quizzes of high school kids in the street that I mentioned is not the result of Japanese pride or the American post-war occupation, but simply kids being kids, nore concerned with modern pop culture than their own cultural history. Of course this is a broad, sweeping generalization of young people, but it is the image of modern youth as depicted in Japan's own media. A national crisis, they say.
On the other hand, I have seen high school debate shows and quiz shows here featuring extremely bright youngsters who are very interested in their country's past as well as its future.
So, I'd wager the modern problem is the same as that around the world: kids just wanna have fun!
