There Morals and Ours
Rudolf Giuliani thinks that whether or not waterboarding is torture depends on who does it saying "It depends on how it's done. It depends on the circumstances. It depends on who does it."
I have nothing to add except the title of this post which is a title of an essay by Leon Trotsky who agreed with Rudolf Giuliani that it depends on who does it. The essay remains interesting as Trotsky was frank about his beliefs and absolutely sincere, the essay was dedicated to his apolitical son who had recently been put to death on Stalin's orders.
I'm pretty sure it's a coincidence that Giuliani gets advice from ex-Trotskyites.
