It depends on your definition I guess, but I have always wondered why someone should be awarded a prize for peace. Would that be thanks for keeping cool even when you’re under duress, or did you somehow stop the fight you started? Perhaps you played the game of politics so well that enemies decide to bury grudge and put their differences aside, or did you change the hearts and mind of people all across the globe to live in peace and harmony? What would be enough for the award of Nobel Peace Prize?
As far I see and know the peace itself is more reward than any prize award.
