why did barack obama win the nobel peace prize

Barack Obama won the Nobel Peace Prize in 2009 for his extraordinary efforts to strengthen international diplomacy and cooperation between peoples. The Norwegian Nobel Committee highlighted his vision for a world without nuclear weapons, his promotion of multilateral diplomacy, renewed emphasis on the United Nations, and his outreach to the Muslim world. They also valued his role in creating a new climate in international politics where dialogue and negotiations are preferred for resolving conflicts. Obama's work on disarmament and arms control, climate change, and human rights were also important factors. The award was seen as an encouragement for his goals rather than recognition of accomplished deeds at that time, as he had been in office less than eight months.
