Like others have said, Jews weren't the only group that didn't fit his standards for the 'Aryan race' That's really what this whole thing was about. He dreamed up what he considers a perfect human race, and that it would be possible to achieve using a form of artificial selection. Not in the sense he bred certain people with certain people, but to make sure the genes and traits he found inferior were not to be spread in the course of his artificial selection.
The further he progressed, the more insane he got. He dreamed to not have the Aryan race in Germany and close by other countries, but to be totalitarian. As for why he found particularly Jews to be inferior, nobody can be sure.
It likely has something to do with the misconception of Jews being the driving force of the great depression, or they got in the way of his plans to fix the economy's inflation. He did very well economically speaking. I think we should seek to strive for his economc principles as long as we find a way to do so without destroying the lives of others.
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.
