I would never hold you personally responsible. I'm a firm believer that we are only responsible for what we have done.
My own experience with Japan and the Japanese came when I spent two years there in the mid-1960's. I was there as an airman in the USAF stationed in Fuchu about 35 miles outside of Tokyo. My best friend was a Japanese who worked on the air base. He had the same name as the president then, Eisaku Sato. Satosan and I hung out together off base and shared a car. (He bought it but I owned it. A whole another story.) We spent many a night getting drunk and carousing around in all the bars and eateries for miles around. He seemed to have a cousin everywhere and knew everyone and it wouldn't cost us anything to eat or drink. I always found the Japanese people to be pleasant to me even though I was an American and this was only 20 years after the end of the war. Fact is, I never thought about the war. I felt like a visitor just doing a job over there.
Anyway,my point made earlier is that we all have two personalities. We can be giving, fair, honest and loving. But there's the dark side of us, all of us. It's good to cleanse the soul when we've done something wrong.
