I didn't say anything yesterday about Petraeus's ascension to CENTCOM commander because I didn't really know what to say, But now I do know what to say: Read Spencer Ackerman. The base question here seems to be whether a general so personally, politically, and philosophically invested in Iraq can step back and view the region as a whole, or whether he'll be so committed to the mission that bears his imprint that he'll shortchange other priorities in favor of devoting ever more resources to Iraq.
