in your world it's prefectly acceptable for higher-ups (and Presidents) to issue Torture orders, it's the grunts fault if they follow it?
(Sidenote: he doesn't make the argument cleanly, imo, that someone very high up issued the Torture orders. If you're arguing that; I'm willing to debate it. The evidence is there, imo, that this was NOT just a few grunts torturing people on their own accord.)
Sadly, this argument continues upwards. Ultimately the President is NOT responsible. He is carrying out the wishes of his boss, the American people. I note that he was re-elected.
