Barack Obama won the 2009 Nobel Peace Prize primarily for his extraordinary efforts to strengthen international diplomacy and cooperation between peoples. The Norwegian Nobel Committee highlighted his vision of a world without nuclear weapons and his work to stimulate disarmament and arms control negotiations. They also recognized how he created a new climate in international politics by emphasizing multilateral diplomacy, the role of international institutions like the United Nations, and a preference for dialogue and negotiations in resolving conflicts. Obama's outreach to the Muslim world, his call for a new start in relations based on mutual understanding and respect, and his support for democracy, human rights, and addressing climate change were key factors. He was awarded the prize just eight months into his presidency, and the Committee hoped the award would boost his efforts on these global challenges. Obama himself described the award as a call to action rather than a recognition of past accomplishments, urging all nations to confront common global challenges like nuclear disarmament, climate change, and peace between conflicting peoples.
