Bill Crawford (who wrote for NRO in Nov.), formerly of All Things Conservative blog, points out to me:

According to an article at ZNET, Sunni Arabs are increasing efforts to “liquidate” Al Qaeda in Iraq, a story largely ignored by the mainstream media. Perhaps most remarkable is the shift in opinion by many Sunnis in regards to Zarqawi and other foreign terrorists. The increased participation by Sunni clans in the fight against AQ in Iraq was proceeded by a shift in attitude towards them. No longer seen as allies, Zarqawi and other foreign fighters are now seen for what they are, terrorists. According to the article, a leader of a terrorist group composed of Iraqis, the Brigades of the 1920 Revolution, said “the rift between the patriotic resistance and the extremists has worsened progressively.” The “last straw” for indigenous terrorists was an attack on police recruits in Ramadi because “there is a need for police” in that city, he said.
