well a half remember fact that there is a relationship between the Nazi and the Middle East groups due to their mutunal hate of the Jewish people so I will not be surprised on that regard with the comparison between ISIS and Nazis.
There's also the commonality that following World War 1, the League of Nations took huge, giant dumps on their ability to rebuild and instill economic progress, which directly caused World War 2. And then following World War 2, they were both shameless divided up between European/Russian interests that further crippled their ability to create a stable region.
So yeah... in those regards, they are exactly like the Germans. Only the Germans benefited from stability of the surrounding Europe, while the Middle East descended into warlord chaos driven by sectarian violence in a region that had previously been one of the most politically stable and culturally diversified empire in Eurasian history.
But yeah, let's just call all Muslims barbarians that should be nuked and not consider that this entire thing is The West's cruel and bloodthirsty actions that sent the whole region to the crapper in the first place.
