Is Bush interfering (and flip-flopping) with Iraq military policy because of the convention?

Despite past criticism of politicians who did not let the military fight the war, Bush appears to be tweaking military policy in Iraq against the will of the military in the field. (That criticism has always been a funny argument to me since we live in a democracy and not a military dictatorship.) I'm not even debating the issue of whether or not it was right or wrong to pull back from Najaf and the fighting, but he is certainly flip-flopping on this issue so he doesn't have to deal with the black eye of 1,000 US dead during his convention.

What many feared about pulling back was the Sadr militants would simply pick up the battle elsewhere and it looks as though it did not take them very long to do so. All of this from a man who doesn't read newspapers or follow the polls. Uh-huh.
