The two biggest factors that have caused the greatest problems on Earth today are: (1) Our monetary system (fractional reserve banking that has all money in circulation representative of debt to begin with) (2) Religion (was responsible for the fiatdom of society before the current monetary system and was responsible for many wars throughout history) The Zeitgeist Movie (mainly the first one) summarized these two factors in a much better way than I ever could. I have independently confirmed the ideas in the movie by way of researching the Federal Reserve Board, and opening any history book to see that religion drove most wars in history.
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.
