Don't think they were Iranians. They were Iraqi Shia with big Iranian support. This operation cost alot o' Dinars. The Iranians don't do their own dirty work in Iraq. They buy it. They use Iraqi Shia proxies. Iranians, as evil as they are, are too damn smart not to create cutouts between themselves and the operators. Ahmed Chalabi is an Iraqi Shia and Iranian agent. The Iranians play a very smooth game when it comes to false flag operations.
That's probably true. These folks just seemed so much - well, slicker than the Iraqis usually are.
I'll bet a new building in murtha's district that he financed it.
