It is … impossible to compromise with the stone-faced propagandists for Bronze Age morality: morons and philistines who hate Darwin and Einstein and managed, during their brief rule in Afghanistan, to ban and erase music and art while cultivating the skills of germ warfare. If they could do that to Afghans, what might they not have in mind for us? In confronting such people, the crucial thing is to be willing and able, if not in fact eager, to kill them without pity before they get started.
I really don't like the phrase "kill them without pity" - I don't like the idea of being either able or eager to kill anyone without pity, which is not to say that I dispute the need in some cases to kill, however regretfully.
But as even the quoted passage shows, Hitchens is talking about the need to fight against Islamist fanatics such as the Taliban. Sparrow does not even seem to consider the possibility that this kind of religious fanaticism, with its very prominent totalitarian and apocalyptic elements, is similar in its malevolence and destructiveness to Nazism. Would Sparrow have complained if Hitchens had advocated warfare against the Nazis in the late 1930s?
Well, yes, he probably would have. Sparrow evidently belongs to the Neville Chamberlain school of political commentary.
It wouldn't hurt to read the entirety of the Hitchens piece, with its detail and its qualifications, before dismissing Hitchens as, in effect, a mere right-wing warmonger. I have my own criticisms of the article, but let's play fair.
