My History lessons at school would have been a lot shorter.
The Nazi-Soviet pact was established because Stalin knew that Germany had a better army, he feared them. After the two years he had gained a big enough army for defense, and could go onto europe. Stalin had very imperialistic goals, Hitler did us a favour, when Stalin got to Berlin an American afterwards asked him if he was relieved to which he replied 'Tsar Alexander got Paris'.
He wanted Europe but now he couldn't do it.
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.
