Al Qaeda knows, and admits, that they’re losing the war. They do think they’ve had some success on one front, though:

The policy followed by the brothers in Baghdad is a media oriented policy without a clear comprehensive plan to capture an area or an enemy center. Other word, the significance of the strategy of their work is to show in the media that the American and the government do not control the situation and there is resistance against them. This policy dragged us to the type of operations that are attracted to the media, and we go to the streets from time to time for more possible noisy operations which follow the same direction.

This direction has large positive effects; however, being preoccupied with it alone delays more important operations such as taking control of some areas, preserving it and assuming power in Baghdad (for example, taking control of a university, a hospital, or a Sunni religious site).

Don’t expect to read about this aspect in the New York Times.
