Nominations for the Nobel Peace Prize are meaningless. The list of who is eligible to submit nominations is in the thousands, it's not a "short list" by any stretch of the imagination, and it doesn't mean more that one person wanted consideration. So every year there is discussion of "person X was nominated for the peace prize!" as if it means something โฆ
Of course, there's the whole other angle that there would be a certain elegance in refusing the Nobel Peace Prize, given its sordid and tainted history as a cabal trophy. Really, who would want to be associated with the rest of the prize winners?
