Robert Kagan's book takes the position that without one dominant power in the world, the policies, norms and order that support the last 60 years of peace and prosperity evaporate. I agree for many reasons. Some of which I will list. 1. Someone has to lead. Most people/nations are stuck in "neutral." There has to be a standard set by someone. Someone has to lead. 2. Democracy doesn't work if the stakes are high.
