imho the nobel peace prize should take into account what is peace, not just focus on the absence of war. this is an outdated idea. Polemology vs. Irenology.
There are so many people contributing greatly to peace who are invisible. only the ones 'fighting against war' are made visible. and with those, like other commentors suggest, its often simply an opinion. one mans terrorist is another mans freedom fighter, and one mans soldier is anothers terrorist... they are all fighting, killing or destroying (destruction can be non-physical here). it should atleast be a nobel anti-war prize or something. not a peace prize. it doesn't do justice to the many people contributing actively to a culture of peace in one way or another.
