Once considered to be Iraq’s worst enemy, Iran has now created, financed and armed the Shiite Islamic movements within southern Iraq. Since the Iraqi Parliamentary elections of 2005, the Shiites have made considerable political gains and now have substantial influence over the country’s U.S.-created military, its police, and the central government in Baghdad. In addition, Iraq is developing economic ties with Iran that Galbraith believes could soon link the two countries’ strategic oil supplies.

That sounds about right. Iraq and Iran have historically been opposed, but a civil war between the Shiites and Sunnis gives a religious edge to this where the Iranians can support the Shiites at basically no cost to themselves. And if we oppose them, we're in opposition to the main group in that "unity government."
