It is incredible that the dysadministration be allowed to get away with this yet again. First of all, the proportion of the IED-related casualties arising from the supposedly-Iranian devices is miniscule. Secondly, even if the devices in question originate in Iran, there is no evidence that Iranians have brought them into Iraq or that their use is state-sponsored. They may just as well have been bought on the black market. And wouldn’t it be in the interests of at least some of the Iraqi insurgents to turn the US’ attention in the direction of Iranian meddling? Encouraging the extension of armed conflict to Iran would further diffuse American power, bog us down even more severely and create the opportunity for a humiliating American defeat an even more humiliating American defeat than we are undergoing now.
