Coming in from the Desert?

Interesting. The day after PM Nouri al-Maliki introduced his “plan for national reconciliation”:, seven insurgent groups from the Ba’athist/Nationalist side of the insurgency have reportedly contacted the Iraqi government in order to offer a truce.
The groups include the 1920 Revolution Brigades, the Muhammad Army (jaysh al-Muhammad), Abtal al-Iraq (Heroes of Iraq), the 9th of April Group, al-Fatah Brigades, and the Brigades of the General Command of the Armed Forces. The seventh group was not named by the Shi’ite legislator who says these groups are seeking the cease-fire.
The 1920 Revolution Brigades is allegedly led by Muthanna al-Dhari, son of Sheikh Harith al-Dhari, who is head of the Muslim Clerics Association, a hard-line Sunni group. Harith al-Dhari’s grandfather was a leading figure in the 1920 revolution and allegedly shot the English Col. Gerard Leachman, sparking the uprising against the British in the west. “I’ve written about _jaysh al-Muhammad_ before”:, and you can read about its place in the greater insurgency.
And here’s a chart from IntelCenter “showing the linkages between the various groups”: (283KB .jpg).
As for the four other groups, I confess I don’t have a lot of data on them.
