According to Nobel's will, the Peace Prize should be awarded "to the person who shall have done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses."

Somehow, at this point in time, I feel that Obama does not meet Nobel's criteria. Maybe you are right, maybe motivating the world is enough. Unfortunately, not much has change as a result of that motivation...Maybe with time. We will see, I hope.
