President Barack Obama, Nobel Peace Prize Winner. Not even one year into office, Obama's international goodwill tour—he's traveled more than any president in history in their first year—has earned him the world's most prestigious award from the Norwegian Nobel Committee. According to the group, Obama's win is thanks to "his extraordinary efforts to strengthen international diplomacy and co-operation between peoples." Obama is the first American to win the prize since 2007, when Al Gore and the UN Intergovernmental Panel on Climate Change shared the award, and the first president since Jimmy Carter, who won in 2002. (Theodore Roosevelt and Woodrow Wilson also won.) Now if only the Olympics Committee met in Norway instead of Denmark.
