Drowning on Dry Land
I dislike Christopher Hitchens for his knee jerk contrarianism and think he's a pompous ass most of the time, but I'll be the first to admit he puts words together very well even when doing so in the service of a stupid idea (see: Iraq, invasion of). With the possible exception of his remarks on the death of Jerry Fawell, his televison appearances usually make me want to smack him. Say what you like about the man, but this took some serious testicular fortitude.
You may have read by now the official lie about this treatment, which is that it “simulates” the feeling of drowning. This is not the case. You feel that you are drowning because you are drowning—or, rather, being drowned, albeit slowly and under controlled conditions and at the mercy (or otherwise) of those who are applying the pressure.
Addendum: While I still think it took some cojones to volunteer to be tortured, especially a second time, I think Chet has it just about right when it comes to how much respect is owed to Hitchens for finally realizing that torture is torture, not an "enhanced interrogation technique" when his nose was literally rubbed in it.
