The Petraeus-ometer

Tom Ricks reads it:

In the decade or so that I've been keeping an eye on Gen. David Petraeus, I've noticed that the more worried he gets, the more boring his public pronouncements become. If I'm right, his mind-numbing appearance yesterday at a Marine Corps conference on counterinsurgency is a leading indicator that he is profoundly worried. One reporter told me after the event that she fell asleep during it. I am guessing Petraeus is fretting primarily about President Obama's public dithering on Afghanistan strategy, but perhaps also about some weird vibes inside the U.S. official establishment in Baghdad.
