And Christopher Hitchens put his own two cents in:
Most fascinating of all is the suggestion that Zarqawi was all along receiving help from the mullahs in Iran. He certainly seems to have been able to transit their territory (Herat is on the Iranian border with Afghanistan) and to replenish his forces by the same route. If this suggestive connection is proved, as Weaver suggests it will be, then we have the Shiite fundamentalists in Iran directly sponsoring the murderer of their co-religionists in Iraq. This in turn would mean that the Iranian mullahs stood convicted of the most brutish and cynical irresponsibility, in front of their own people, even as they try to distract attention from their covert nuclear ambitions. That would be worth knowing. And it would become rather difficult to argue that Bush had made them do it, though no doubt the attempt will be made.
If we had withdrawn from Iraq already, as the “peace” movement has been demanding, then one of the most revolting criminals of all time would have been able to claim that he forced us to do it. That would have catapulted Iraq into Stone Age collapse and instated a psychopathic killer as the greatest Muslim soldier since Saladin. As it is, the man is ignominiously dead and his dirty connections a lot closer to being fully exposed. This seems like a good day’s work to me.
