If you have time, take a look at "An Honest Victory" by ex-Marine Nathaniel Flick. I don't agree with much of what he says, but I like this:
As things stand, American citizens - and the military - have been offered a false choice between "staying the course" in Iraq and precipitous withdrawal.
This puts the aimpoint smack on the center of the Rovewellian "limited choices" propaganda we've heard since day one with this administration. It was "invade Iraq or do nothing" before. It's "get the job done or slink away" now.
Clearly, now as then, we have a wide range of "courses" to choose from. But before we can truly evaluate them, the administration must come clean with us on what the "job" we need to get done consists of.
