The decline of Europe means a world with a greater diffusion of power and a lessened ability o create international norms and rules of the road. It also means that America’s superpower status will linger. Think of the dollar. For years people have argued that it is due for a massive drop as countries around the world diversify their savings. But as people looked at the alternatives, they decided that the chief rivals, the euro and the yen, represented economies that were structurally weak. So they have reluctantly stuck with the dollar. It’s similar dynamic in other arenas. You can’t beat something with nothing.
