George Bush made a mistake when he referred to the Saddam Hussein regime as 'evil.' Every liberal and leftist knows how to titter at such black-and-white moral absolutism. What the president should have done, in the unlikely event that he wanted the support of America's peace-mongers, was to describe a confrontation with Saddam as the 'lesser evil.' This is a term the Left can appreciate. Indeed, 'lesser evil' is part of the essential tactical rhetoric of today's Left, and has been deployed to excuse or overlook the sins of liberal Democrats, from President Clinton's bombing of Sudan to Madeleine Albright's veto of an international rescue for Rwanda when she was U.S. ambassador to the United Nations. Among those longing for nuance, moral relativism--the willingness to use the term evil, when combined with a willingness to make accommodations with it--is the smart thing: so much more sophisticated than 'cowboy' language.
