MUCH OF THE DISCUSSION about recent Iraqi operations against illegal Shia militias has focused on issues about which we do not yet know enough to make sound judgments, overlooking important conclusions that are already clear. Coming days and weeks will provide greater insight into whether Maliki or Sadr gained or lost from this undertaking; how well or badly the Iraqi Security Forces performed; and what kind of deal (if any) the Iraqi Government accepted in return for Sadr's order to stand down his forces. The following lists provide a brief summary of what we can say with confidence about recent operations and what we cannot.

What We Know:

* The legitimate Government of Iraq and its legally-constituted security forces launched a security operation against illegal, foreign-backed, insurgent and criminal militias serving leaders who openly call for the defeat and humiliation of the United States and its allies in Iraq and throughout the region. We can be ambivalent about the political motivations of Maliki and his allies, but we cannot be ambivalent about the outcome of this combat between our open allies and our open enemies.

* The Sadrists and Special Groups failed to set Iraq alight despite their efforts--Iraqi forces kept the Five Cities area (Najaf, Karbala, Hillah, Diwaniyah, and Kut) under control with very little Coalition assistance; Iraqi and Coalition forces kept Baghdad under control.

* Sadr never moved to return to Iraq, ordered his forces to stop fighting without achieving anything, and further demonstrated his

* Maliki demonstrated a surprising and remarkable commitment to fighting Iranian-backed Special Groups, Sadr's Jaish al Mahdi (the Mahdi Army, or JAM), and even criminal elements of JAM. The Iraqi Government has loudly declared that "enforcing the law" applies to Shia areas as well as Sunni. Maliki has called Shia militias "worse than al Qaeda." These are things we've been pressing him to do for nearly two years.

* We've said all along that we did not think the ISF was ready to take care of the security situation on its own. Maliki was overconfident and overly-optimistic. But for those who keep pressing the Iraqis to "step up," here's absolute proof that they are willing. Are we willing to support them when they do what we demand? Can anyone reasonably argue that they will do better if we pull out completely?

* On March 30, Sadr ordered his followers to stop fighting. This decision contrasts with his 2004 decision to fight on, and his continued presence in Iran combined with this surrender results from weakness, rather than strength.

* The ISF operation did not clear Basra or destroy either Special Groups or the Mahdi Army.

* But the ISF performed remarkably well, moving numerous units to Basra on short notice, establishing them in the city, engaging in hard fighting, and stopping only when Sadr caved.

* Special Groups launched concerted attacks in Baghdad and in the Five Cities area (the Shia heartland), but were repulsed by ISF forces acting almost alone in the Five Cities area and by a combination of ISF and Coalition forces in Baghdad.
