I'll excerpt a few of the good ones of his list of 21:
Powerful states often do bad things. When they do, government officials and sympathizers inevitably try to defend their conduct, even when those actions are clearly wrong or obviously counterproductive. This is called being an "apologist," although people who do this rarely apologize for much of anything.
Some readers out there may aspire to careers in foreign policy, and you may be called upon to perform these duties as part of your professional obligations. Moreover, all of us need to be able to spot the rhetorical ploys that governments use to justify their own misconduct. To help students prepare for future acts of diplomatic casuistry, and to raise public consciousness about these tactics, I offer as a public service this handy 21-step guide: "How to Defend the Indefensible and Get Away With It." The connection to recent events is obvious, but such practices are commonplace in many countries and widely practiced by non-state actors as well.
Here are my 21 handy talking-points when you need to apply the white-wash:
4. Ok, we did it but it wasn't that bad ("waterboarding isn't really torture, you know").
5. Well, maybe it was pretty bad but it was justified or necessary. (We only torture terrorists, or suspected terrorists, or people who might know a terrorist...")
7. Besides, what we did was technically legal under some interpretations of international law (or at least as our lawyers interpret the law as it applies to us.)
18. It's a tough world out there and Serious People understand that sometimes you have to do these things. Only ignorant idealists, terrorist sympathizers, craven appeasers and/or treasonous liberals would question our actions.
Time to go read the whole list, don't you think?
