Mario Loyola of NRO explains that NWA had it right all along:
This refusal to recognize any central monopoly of violence is of course what doomed all the negotiations. It was also the central element of Hamas’s political program. And naturally, what it means is the negation of statehood, because the most essential foundation of a state is the ability of central authority to claim a monopoly of legitimate violence.
And that, in a nutshell, is why I am anti-statist. A monopoly on anything, but especially violence, (however “legitimate”), is always a very bad thing.
