Then what is your evidence that the opposite will happen?
I did not offer that the opposite will happen, and I gave you the evidence of what I believe will happen.
What the neo-cons really fear is a Persian super-state that is hostile to US interests in the Middle East. Such a state would represent no credible threat to the United States itself, but would be a problem for American adventurism in the Middle East. Since that is a subtlety that is lost on the adoring followers of the neo-cons, they simply substitute the hysterical claim that leaving Iraq would result in Sharia in the US almost overnight. It is unfortunate that most of these people don’t bother to question the sublimely ridiculous nature of these claims nor do they examine the evidence to attempt to glean the more likely outcomes.
