Talk about a study in contrasts. On Friday jailed Chinese dissident Liu Xiaobo was awarded the Nobel Peace Prize for trying to bring greater personal freedom and human rights to his homeland — efforts that currently have him serving an 11-year sentence in a Chinese jail. Liu has been in and out of prison over the years for his activities. He’s just the third Nobel winner to receive the award while imprisoned, and Chinese officials welcomed the news by implementing a blackout on his selection inside the country. Now the contrast — the one between Liu, recognized for a life of self-sacrificial (and dangerous) work for individual liberty, and last year’s winner, President Obama, recognized for … well, the potential to do great things.
