David Scheffer also has a provocative op-ed in the International Herald Tribune today which you can read on the mirrored NY Times site: http://www.nytimes.com/2012/02/24/opinion/defuse-the-lexicon-of-slaughter.html?_r=1
In it he writes:
Using the word “genocide” loosely can be tragically ineffective or self-defeating. It can intimidate powerful nations from reacting quickly enough to prevent further atrocities….By forgoing “genocide,” politicians would no doubt disappoint interest groups determined to use the label to describe the suffering inflicted on their ancestors. The Armenians, in particular, would find this compromise hard to accept. But their strongest case rests with the historians and the jurists now — not with the politicians whose loose indictments trigger the very tensions that can ignite prejudice among peoples and nations. Shifting to “atrocity crimes” in government speech, meanwhile, would focus the efforts of officials on getting more unified international responses to ongoing massacres.
