Which Nobel Peace Prize winner was least deserving?

[Cassius]

Obama, on the basis of the fact he literally did nothing prior to being awarded the prize. All the others can be criticised on the basis of their records and whether they actually created ‘peace’, but at least they all did something and attempted to make strides to some kind of cessation of hostilities prior to their receipt of the prize.

The Nobel Peace prize is a particularly ridiculous award anyway, as its track record amply demonstrates (and in part because, unlike the literature and scientific prizes, it doesn’t sit comfortably at one or the other pole of the objective-subjective scale). The Economics Prize is of similar value, given its strong track record of awards given to people who were later made to look very silly indeed (Modigliani, Miller, Lucas, Merton and company).
