"As he (Obama) made his hajj from Strasbourg to Prague to Ankara to Istanbul to Cairo and finally to the U.N. General Assembly, Obama drew the picture of an America quite exceptional — exceptional in moral culpability and heavy-handedness, exceptional in guilt for its treatment of other nations and peoples. With varying degrees of directness or obliqueness, Obama indicted his own country for arrogance, for dismissiveness and derisiveness (toward Europe), for maltreatment of natives, for torture, for Hiroshima, for Guantánamo, for unilateralism, and for insufficient respect for the Muslim world".
That, in two sentences, explains why Barack Obama was awarded the Nobel Peace Prize today. Now the Nobel Committee couldn’t quite come out and say that directly. BUt Krauthammer did it for them before the news!
