Glenn, two points - why are you not pleased that Klein seems to have shifted his opinion to more closely match yours? Is this not the goal of an opinion writer, to win people over to your side? So what is the complaint?
Secondly, the first citation of Klein you listed was made in 2002, which is before Klein, as well as most people, knew what was going on in Abu Graib, so how should he be held to account for developing an opinion based on the available facts?
