MHO, much of the horror that resulted from the rise of Japanese Imperialism can be laid at the doorstep of Shintoism.
Jar,
I would suggest even more of that horror should be laid at the doorstep of Britain's imperialistic devastation of China. Will Durant in his first volume of the Story of Civilization was writing before WWII. He predicted that Japan would go to war because Japan saw what Britain did to China, the opium wars, etc and realized that it could either be forced into being a colonial state, or become an imperialist itself, and to do that it needed raw materials. Durant predicted Japan would go to war. How is that for successful prophecy?
Much of the fighting and terrorism in the world is stemming from British colonialism, from Northern Ireland to the middle east. And for my bias I will state that I am a born in America of British and Scots/Irish descent.
Imperial Japan and Germany were examples of highly authoritarian cultures. I note that the fundamentalist on this list seem to feel authoritarianism is neccessary for a moral culture. Certainly the writers of the Bible claimed their god demanded genocide of them. This was more wishful thinking than fact however, as there is no evidence of Moses, Jericho, or an invasion of Canaan by Israelites.
Interestingly the Mongols converted to Buddhism and became peaceable.
How wonderful it would be if the Jews, Christians, and Muslim would also convert and live compassionately and non violently with one another.
peace,
