Dean Esmay explores fears of a "Global Caliphate," or a Muslim dictatorship stretching across the Middle East and beyond:

This is like asking your average American if our own laws should be guided first and foremost by the Bible. I imagine you could get a good half of Americans to agree on that. But can you get even 10% of them to agree on exactly what that means? In anything but the most broad and nebulous terms? I doubt it. ...

To get your global Caliphate you're going to need a Global Islam, and there isn't one. Just endless splinters and factions and endless debate and argument. Yeah yeah, there's one Koran. And multiple interpretative traditions of it, multiple Hadith sets and subsets and views of same, multiple cultures, multiple languages, and multiple fragmented self-interest conflicts, economic and otherwise. Add together the differences in language, culture, ethnicity, and sheer geographic logistics, and the profound differences between Muslims themselves, and you're positing an idea with no practical possibility of happening.
