That's not what the author is proposing though.
I think that, fundamentally, any 'solution' in Iraq that proposes 'choosing' one ethnic or religious bloc to support over the others is certain to fail.
The author never says though that we should put a Sunni in charge of Iraq though.
As for the final solution to Iraq I am no longer sure, I lose more and more faith in the Shia led government by the day.
