At least with Iraq, proponents of "Iraq forever!" generally had pleasing stories to tell. That is, crazy or not, they had a plausible sounding justification for why we were there and why we needed to stay. I guess this was in large part due to the Bush message machine and lockstep Republican/conservative mouthpieces, but it did create a degree of plausibility. I don't know how fast we're really going to draw down forces in Iraq, but at least the trend seems to be going in the right direction.
But with Afghanistan... it's... what? I guess someone would have to try to explain just what the fuck we did for the past 8 years before attempting to explain how... now it's going to be different!
At least, maybe, Obama's skeptical...
