The first Nobel Peace Prize was awarded to the Swiss Jean Henry Dunant, founder of the International Committee of the Red Cross (ICRC), in 1901. The ICRC was always committed to defuse conflicts by negotiation if possible with all involved parties of the conflict.
2009 U.S. President Barack Obama received the Nobel Peace Prize. Through this award he became a synonym for an new world order for peace.
2011 Nobel Peace Prize Laureate Barack Obama had killed the wanted terrorist Osama bin Laden in an extra-legal action by a hit squad.
Osama bin Laden was a wanted terrorist and action against him will more than likely have been justified. But is a world in which a Nobel Peace Prize Laureate can send out hit squads, a world that stands for peace? Do not forget: the Nobel Peace Price is the highest price you can get awarded for acts of peace.
Of course it is not the fault of Obama that he received the Nobel Peace Prize quasi prematurely. And as President of the United States, he has to make decisions that are very difficult and are of great importance. But: should the Nobel Peace Prize remain a predicate for for peacekeeping operations in the sense former Laureates like Martin Luther King, Nelson Mandela, Mother Teresa or Aung San Suu Kyi taught us, then future laureates must first have a proven record. Premature praise may not be enough.
