Neptunus Lex is new to me but famous within the WarBlogging community. This is typical of his writing:
The Sunnis know now, they must, that they will never again be able to install a strongman of their choosing atop a cowed Shia majority, and many have now ranged themselves against the al Qaeda-allied foreign fighters with whom once they cast their lots, recognizing at last the smothering austerity of the jihadist vision. Still, feeling disempowered, disenfranchised and petulant they apply the only lever they feel they own and retreat to the kind of perverse political violence which threatens to swallow them up in its consequences.
He calls for the destruction of al Sadr's army.
UPDATE: You know, the more I think about it the more I think he's put his finger on the problem we're having with the Arabs, except that he's wrong. Yes the Sunnis "must" know, but they don't. The whole Arab world is so taken up with denial and conspiratorial thinking that they can deny absolutely anything. If majorities of Arabs laud Bin Laden for attacking the USA while simultaneously denying Arabs were responsible for 9-11, and they do, then why should it surprise us that Sunnis would deny the impossibility of their ever taking over Iraq again? On the other hand, his solution, the absolute destruction of al Sadr's army through forthright violence, is what it will take to beat it into their thick Arab skulls. Like a lot of Americans, I've had about enough of the Mr. Nice Guy Hearts & Minds routine.
