The political belief was Fascism; Nazism is something else. The two go together well but they are not the same thing, nor is one inevitable where the other exists. The Nazi party was the official political party in Germany; there were some 6 million members by 1944.
In the earlier stages of WW2 most of the soldiers would have been members of the party. I agree with those who say to call all Germans Nazis is wrong, likewise to say Nazis were German. Nazi Germany is as close to accurate as we're going to get.
By the time it fell, Nazism was pretty widespread in Germany; much more of a cultural force than could be said of either of the main parties here - now or then - or in the USA. Things like the Hitler Youth began well before WW2 and had a powerful effect. To characterise the Italians as ideologically or politically equivalent to Nazi germany is also wrong.
Italy was Fascist - as was Spain, and there was a fascist movement in the UK. Again, another answerer has stated that the Nazis ... more.
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.
