The Norwegian Nobel Committee has suddenly seen the light. After a near-death experience last year, when it awarded its coveted Peace Prize to President Obama, the committee has redeemed itself, and the future of the prize, by honoring Liu Xiaobo. The Peace Prize has always tilted leftward: remember that recent winners have included not just Obama but Al Gore and Jimmy Carter. Selecting Liu Xiaobo, by contrast, is a real game-changer. Instead of bowing to the powers that be, the Nobel Committee is challenging the most oppressive power of all: the Communist Party of China.
