The Peace Prize is purely political, complete with a stated political agenda, while the others have always been politicized. Not so much now, but a lot more in the past.
Seamus: Apparently the reasoning behind giving it to the opcw was to give the effort against wmd's a push, and I can't really see what giving the prize to Malala would've pushed. An inspiration for muslim women around the world to fight for their rights? Tawakkul Karman got that prize in 2011, it's too soon for a repeat.
