'The clear purpose of the "special groups" alarm is to implicate Sadr as an Iranian agent'

From: Endless Enemies by Justin Raimondo

It used to be that the Sunni "dead enders," as Donald Rumsfeld called them, were the face of the enemy in Iraq. Then the administration very quickly learned that in order to sell the war to the American people, they had to somehow connect it to the 9/11 terrorist attacks and Osama bin Laden, and so al-Qaeda in Iraq – a group that never existed prior to the invasion – was given top billing. But what are these "Special Groups" who have suddenly stolen the limelight?

Supposedly they are armed "rogue" elements of the various party militias that have been funded and trained by Iran, and – significantly – Lebanon's Hezbollah organization, to carry out terrorist activities in Iraq, and, presumably, kill American and Iraqi government soldiers. An elaborate demonology has grown up in the War Party's circles to buttress this shaky and ill-defined concept: go here, here, and here to examine its many twists and turns. This narrative is a variation on the Israeli worldview, which sees all the various Muslim and pan-Arabist groups in the region as essentially tentacles leading back to the same octopus head.
