Romey Versus the Jihadists

I think there's pretty good reason to believe that Mitt Romney's conduct of foreign policy would be better than Rudy Giuliani's, which is precisely what makes the kind of rank ignorance on display here so frightening:

The idea that we should be laying awake at night afraid that a group of at most several thousand people who control almost no territory or valuable military equipment might establish a universal caliphate or "collapse freedom loving nations like us" is ridiculous. Al-Qaeda's goals are absurd, and obviously so, and one ought to say so confidently. The fact that a relatively small group of people with lunatic goals can nevertheless knock down giant office buildings and murder a huge number of people is, indeed, something to be afraid of but not nearly on the grand geopolitical level Romney is postulating here.

On top of that what does this have to do with Iran?
