Progress In Iraq? Infighting Among Terrorists

This didn't get much press (shocking I know), but I found it fascinating. Bill Roggio writes about "Faultlines in Iraq's Islamist Insurgency". In particular:

al-Qaeda in Iraq has recently issued a statement claiming to “have set up an umbrella body to coordinate their fight against U.S.-led forces and the Iraqi government.” Notably excluded from this body of insurgent groups are Ansar al-Sunnah and the Iraq Islamic Army.

Zarqawi was able to secure the commitment of a little known Islamist group called The Victorious Sect and five small organization, however he was unable to reach out to two largest groups, Ansar al-Sunnah and the Islamic Army in Iraq, two groups that have worked with al-Qaeda in the past.

Couple this story with Bin Laden's rejected (and disingenuous) call for a truce, and I can only see more progress in Iraq.
