Obama accepts Nobel Prize

President Obama accepted his Nobel Peace Prize earlier today -- and explained that while peace must be pursued, war is sometimes necessary. "For make no mistake: evil does exist in the world. A non-violent movement could not have halted Hitler's armies," said Obama. "Negotiations cannot convince al Qaeda's leaders to lay down their arms. To say that force is sometimes necessary is not a call to cynicism - it is a recognition of history; the imperfections of man and the limits of reason."
