Well thats isn't really 100% true good sir. Yes they had some things in commen but the Nazi party stands for Nationalist Socialist German Workers party. Its socialism with natiolistic elements. One difference was also that under the nazi party you could have some private ownership and under communism it total goverment controlled landgrab. Hitler even blamed the communist besides the jew for Germany's problems. Although lenin agreed that the ultimate conclusion to socialism is communism. I think Hitler kind disagree with that claim. But the parralels are there tho so I understand in it broader sense they are the same. But in reality there are many differences. With what I agree is that they are both left ideas.
