I think you've missed something here... like a brain. Z.
Japan has strict laws regarding crime, it has strict laws regarding immigration (if you're a felon, you're not allowed into Japan), the police are the only one's with guns in Japan. The Japanese have always been very intelligent, just look at how they got the torpedoes into the shallow waters of Pearl Harbor in 1941, just look at the technology they have created. Most of Japan is SHINTO.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
