Why do most Americans bash Germans in WW2 for Holocaust but don't bash the Japanese for their crimes in WW2?

The Holocaust includes all non Germans, Jews, Poles, Roms/Gypsies and any country of people under occupation. The war was fought to to rescue European countries from domination by Nazi Germany under Hitler. The movie takes some liberties, there are better movies about the Holocaust see Schindler's list and books.

Also on the reasons for going to war as allies of counties in Europe.

No World War 2 started before the Holocaust.

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.
