"And as for his claim that the Islamic State "is certainly not a state," the President's tone is rather too defensive. He says "it is recognized by no government, nor by the people it subjugates," but none of these factors are relevant in determining what constitutes a state–which is nothing more or less than a monopoly on the use of force in a given territory. The horror that is ISIL is merely the process of state formation looked at up close: the terror they employ is simply an exaggerated rendition of how every state gains its "legitimacy"–by definitively establishing its coercive monopoly. While ISIL is doing so in a particularly graphic manner, in principle it is acting no differently than any other embryonic state in history, benign creation myths to the contrary notwithstanding."
