Brian Beutler and Mathew Yglesias have been reading David Petreaus's Ph.D. dissertation, and they don't much like it. Beutler calls it a "fantastic exercise in saying nothing," and Yglesias seems to agree.
I must say I am inclined to agree with James Fallows, who characterizes their complaints as "silly." This whole exercise is pointless. So what if his dissertation was bad? Next they'll be telling us that we need to reassess Patton's tenure as commander of Third Army because he was a lousy poet.
