I have a proposal: we hear that the Iraqis say the torture was so bad it made them feel like a woman. Being a woman is the worst thing possible, you realize.
But, being treated as if you are a woman probably isn't banned by the Geneva conventions. So: to soldiers interested in getting prisoners to break, I suggest you treat them like women. Refer to them with feminine pronouns, switch out their clothing for girly stuff... apparently, that's the worst kind of torture there is!
(Hey, it might not work, but then maybe we'll end up with the Iraqi resistance composed entirely of transvestites, and that would at least be more amusing!)
