In most of the press reports I’ve seen on the administration’s no-names-allowed press briefing on Iranian arms transfers to Iraq, reporters have noted skepticism about the administration’s credibility. But I’ve seen few press reports which specifically note what seems to be the biggest hole in the administration’s argument — namely, that Iran supports the Shi’a militias but most of our troops are being killed by Sunni insurgents. As Juan Cole notes, the numbers simply don’t add up. That doesn’t mean that Iranian made weapons aren’t killing American troops. What it suggests is that they’re getting into insurgent hands through black market channels rather than through the Iranian government itself. (Consider: How many weapons in Iraqi insurgent and militia hands do you think were made in the USA?)
Perhaps there’s some reason why this seeming gap in the administration argument isn’t really a gap at all. But it at least seems worth a lot more explanation. And I’m not seeing it.
