I was under the impression that the treaty of versailles was the most important aspect of the reasoning behind the beginnings of ww2.. as Darken said. Part of the bring back of "the glory of germany"..
I thought Germany was doing great before they entered the war, they had climbed out of the mud pit ww1 had left them in..
the allies were hated, as were the jews and communists.. because they brought down the the great glory .. and caused sufering.. -the results of the treaty-.. and results of the invasion and over taking of german economy from the jewish people..
I think perhaps the treaty is a very important part of the beginning...
