The "Islamic State" is Neither

At the core of Muhammad's life was the quest for an all-in-one society, in which politics, religion, art, and economics all flow from one, central authority derived from the word of God. It is not anti-Muslim or anti-Islamic to say that Muhammad did not seek freedom of religion or pluralism; he believed he had found the answer, and he wanted to apply it.

For the "hyper-violent" adherents of the group called the Islamic State to call for such a thing, then, is deeply rooted in the traditions and philosophy of Islamic culture. Muhammad did the same, and he fought more than one serious, literal battle to achieve its creation. That he succeeded in doing so is one of the things that sets Islam apart from other world religions, and it infuses the faithful with a distinct, though not unique political mindset (one not at all different from that of most Israelis.)

But what would the government of such a group look like? For one, it would erase or diminish the lines drawn more-or-less arbitrarily by the Sykes-Picot Agreement of the early years of the last century. It would be exclusively Sunni, as Iran is fully aware, and authoritarian at least. It would not be open to diversity, and it would not be an especially willing partner with the United States in maintaining Western interests.

So far, IS has spent all its time rebelling against the status quo, and so has not established anything like a state as yet. It governs nothing, eve as it expands the reach of its military domination and intimidation. Most commentators assume that it will be takfiri and brutal. Al Qaeda itself has disavowed many of its methods as too nasty, and while that group has ulterior motives for such remarks, it's still saying a lot that Zawahiri flinches at their violence.

If these rebels act anything like takfiris elsewhere, they are not leading in the tradition of Islam. Muslim tradition allows excommunications and attacks on apostates, but Muhammad was a statesman as well as a profit, and he impose strict rules of evidence and procedure on such practices. Here is the Q'uran itself:

O you who believe! When you go (to fight) in the Cause of God, verify (the truth), and say not to anyone who greets you (by embracing Islam): "You are not a believer"; seeking the perishable goods of the worldly life. There are much more profits and booties with God. Even as he is now, so were you yourselves before till God conferred on you His Favours (i.e. guided you to Islam), therefore, be cautious in discrimination. God is Ever Well-Acquainted with what you do. (4:94)

That is, one can not simply wander around the desert killing people on his own initiative, as these people have done. Until they prove themselves to be true Muslims, then, they will gain no legitimacy, and no statehood.
