Confront Ahmadinejad about his cognitive dissidence -- if Ahmadinejad believes the Holocaust happened then it shoots down his theory that "the Joos" are powerful beyond words and run the world.
A race of people can't be at one and the same time, more powerful than all others, and victims burned to death in ovens.
In Ahmadinejad's mind, he has to believe the story of the powerful "Joo" - the "Joo" who keeps all Arab and Persian cultures broken, poor, and humiliated. If Ahmadinejad were to look closely at reality, he would see that dictatorships all over the world are poor - and their citizens unhappy. When that's mixed with politically powerless women, 7th century ideas, a total lack of freedom, the results are the same: backward, ignorant, helpless, poor, angry countries. It's not the US, it's not the "joos" it's their choices. It's Muslim choices that are their own downfall.
The recipe for failure? An oppressive religion, thuggy men, powerless women and limited to nonexistent freedom. They create the failure. Their choices make Muslim countries into the totalitarian failures they are -- Ahmadinjad and Islamic fascism are lies -- lying to themselves -- lying to us. We must not buy into it.
My sense of where we are is 1) either we help them deal with the totalitarians in their societies (and I can barely work up any enthusiasm for risking our sons lives to do that) or 2) we destroy Islam militarily. I would prefer number 1 to work, and want to give Islam a chance to reform itself. That said, I give it less than a 50-50 chance of working. After another major attack on the US it will be time for number 2. No one gets to change my religion by force or threat of force.
