From today’s Times. This isn’t good:

That is not just a question of numbers. Some American military officers say they believe the Iraqi Army may be more effective than the Iraq police, and more trusted by local citizens. Yet several Iraqi battalions have deserted rather than follow orders to go to Baghdad, according to American military officials. In the case of these units, summoning them to the Iraqi capital was tantamount to demobilizing them.

Here’s more on the “holding” failing in “clear-and-hold”:

The original concept behind the plan was that American forces were to hold cleared areas for 60 to 90 days, during which the process of economic reconstruction would begin. Then American forces would turn the sectors over to Iraqi police and army units, freeing up American troops to tackle security challenges elsewhere in the city. Without sufficient Iraqi forces, however, this process has been hampered and it has been more difficult to prevent militias and insurgents from sneaking back into cleared areas.
“What takes the combat power is the holding piece,” said General Thurman. “We can do the clearing. But once you clear if you don’t leave somebody in there and build civil capacity in there then it is the old mud-hole approach. You know the water runs out of the mud hole when you drive through the mud hole and then it runs back in it.”

Finally, some options for more troops:

There are a number of ideas being discussed in private to fix the plan. Americans still hope to receive additional Iraqi Army forces next month. They also hope to persuade the Iraqi government to purge police stations infiltrated by militias. Iraqi deployment areas may also be realigned.
American forces have already shifted some forces to new high-violence sectors and may make further adjustments. Shrinking the military zone controlled by the American Baghdad-based division, which now extends south to the cities of Najaf and Karbala, has also been discussed as a way to increase the density of American troops in the capital.
Erecting more barricades to section off parts of the city has been proposed by some officers. So has legitimizing some neighborhood watch organizations. That idea cuts against the policy to abolish militias but has been advocated by some military officials as a useful expedient.
Keeping the Army’s Fourth Division in place in Baghdad instead of rotating it home when it is to be replaced by the First Cavalry Division would substantially increase the number of American troops in the city. But there have been no indications that such an idea is under serious consideration.
