There’s an interesting little aside at the end of this essay by Christopher Hitchens on Hersh’s fantasy:
So a Sarin-infected device is exploded in Iraq, and across the border in Jordan the authorities say that nerve and gas weapons have been discovered for use against them by the followers of Zarqawi, who was in Baghdad well before the invasion. Where, one idly inquires, did these toys come from? No, it couldn’t be.
Oh, but it could, couldn’t it?
