Why Obama's Iran policy will fail

Here's an interesting and different take on why President Obama's 'engagement' policy in Iran will fail. Mr. Obama's problem is that Mr. Khamenei could only have chosen Ahmadinejad because he does not want friendly talks with the U.S. He evidently calculates that without the ideology of "anti-Americanism" the regime would collapse. He is right.Certainly religious support cannot be enough anymore.
