by Anne Applebaum, Slate Magazine, USA - Invoking the Nazis also changes the tenor of a debate. There may be good, tactical reasons for choosing not to negotiate with Hezbollah or the Iranian regime, for example (the best reason, usually, is that the relevant diplomats are fairly sure that negotiations won't work). But calling opponents of this policy "appeasers" distorts the debate, giving tactical choices a phony moral grounding. In reality, circumstances do change, even where "terrorists and radicals" are involved, as this administration in particular knows perfectly well.
