Yeah, and let's not forget a certain Adolf Hitler was nominated for the peace prize as well. The peace prize has never had any credibility IMO.
They have no control over who is nominated, so that shouldn't be used to tarnish their image.
Having said that, their choice of 'winners' in recent years has made the Nobel Peace Price a joke.
The Nobel Committee should return to it's roots of just awarding prizes for science (and Economics is hardly a science).
