No hard feelings

Abu Omar al-Baghdadi, the head of the Islamic State of Iraq, issued a statement in response to criticisms from the Islamic Army and others complaining about intolerant and aggressive behavior by ISI people against non-ISI resistance groups. Marc Lynch outlines the initial summaries of it. The text is available here. Here is my version of the section where al-Baghdadi addresses those groups by name:

To our brothers in the Ansar al-Sunnah army and the Army of the Mujahideen: The love that is between us is deep, and the bonds of our conviction and our attachment are not something vulnerable to adversity. To our sons in the Islamic Army: Know that I would sacrifice my blood and my honor for yours, and by God you will not hear of us anything but good. So be of good spirits and investigate us, because the that which joins us is stronger than some imagine, may God forgive them. And to the soldiers in the 1920 Brigades, yes, it is true that the satanic Islamic Party has put the insinuations of the Devil between us, but the leaders of your brigades understood and they sat down with their brothers in the Islamic State to disenable the fuse of fitna and scatter the seeds of love, and...[I am obligated] to spare your blood and that of every muslim who has not incurred heresy in spirit or in blood. Fear God and don't forget that ultimately it is the word of God that is the highest, and not the nationalist (wataniya), and not the loathesome racial (qaumiya). ...you are all equally responsible for it [the word of God] on the day of resurrection.

In specific terms, he acknowledges there was a problem between his people and members of the Brigades of the 1920 Revolution, which he attributes to the meddling of the Islamic Party, no doubt referring to proposals for negotiating with the Americans. I think it could be significant that al-Baghdadi refers to this issue, but not to any others. This would be contrary to statements issued recently by various government people implying a much wider range of negotiations. (For instance, just today Maliki issued a statement to the effect the government is negotiating with several resistance groups, which he didn't name, but which the Aljazeera.net reporter says probably include Islamic Army, 1920 Revolution Brigades, Army of the Rashideen, and others).
