You're right there Wolfgang - I should have checked better before posting - I did think Teribus had used those words, and he didn't.

He did write "I don't believe that the Sunni population of Iraq deserve anything, they are the equivalent of the hard-line Nazis in Germany, in 1945.", but that's not quite the same thing, and in fact he seems to have been meaning they deserved no share of oil revenues in any breakup of Iraq.

Rather analogous to the proposals which were made by some for deindustrializing Germany as collective punishment for Nazism - drastic and potentially disastrous but not with quite the genocidal implications carried by the mistaken quote.
