Hitler truly was a great leader, though he made mistakes like any other human being. We can include the unnecessary attack on USSR, in 1941. That opened way for more war, and Nazi Germany already had enough of it. It brought Germany to its ruin, and they lost the war to the Allies. This war Hitler's biggest mistake, which concludes he did do something wrong, both for him and his people.
In my imagination, my opponent would use logical arguments for the debate, even being his views different from the majority of the population in the world. Let this unfortunate debate end, then, and please vote Con. Thank you! =)
