Just win, baby!

"Victor Davis Hanson:

At some point all these retired generals need to simply quiet down and think. In World War II, Nimitz or Eisenhower never blamed the Secretary of War or FDR for the mistakes on Iwo Jima or the Kasserine Pass. Instead, they called in their top brass, drew up a plan, followed it, and then presented a successful fait accompli to their civilian overseers. In other words, our four-stars need to summon their colonels and majors in the field, draw up a military strategy that ensures our political aims of seeing a stable consensual Iraq, and then win. Blaming Bush, or faulting Rumsfeld is a waste of time; figuring out as military officers how to achieve victory over a canny enemy is all that matters."

I think that this assumes that the civilian leadership is willing to listen to the recommendations, I think that's assuming a lot.
