Adolf tler and his Nazi regime wanted Lebensraum or "living space". Basically, the Nazi Germans wanted to create a great empire larger than the world had ever seen before. The fact that they had to torture, maim and murder to create their 1000 Year Reich didn't raise an eyebrow among Nazi faithful tler justified invasion of Poland by the need to recover lands lost in WWI, and the city of Danzig among others, but the truth was he needed to peruse his goal of his belief in Aryan race expansion, and he started reasonably from the weakest neighboring country, apart from earlier peacefully annexed Austria and Czechoslovakia.
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.
