...about the really, really bad idea to dribble troops in to Iraq. Fred Kaplan:

The upshot is that Kagan's[/Bush's/McCain's/Lieberman's - J] surge involves more troops than the United States can readily mobilize and fewer troops than it needs for the kind of victory he has in mind....

Either way, where are they coming from? It's worth emphasizing that Kagan calculates that at least 150,000 combat troops will be needed to secure Baghdad alone. In all of Iraq, he estimates, the United States has only 70,000 combat troops now. [Emphasis mine.]
