The power vacuum that's killing the eurozone

We are realizing just how much international economic order depends on the role of a dominant country — sometimes known as a hegemon — that sets clear rules and accepts some responsibility for the consequences. For historical reasons, Germany isn’t up to playing the role formerly held by Britain and, to some extent, still held today by the United States. (But when it comes to the euro zone, the United States is on the sidelines.)

THERE appears to be a power vacuum, and the implications are alarming. We may be entering a new world where international cooperative arrangements, in environmental areas as well as finance, are commonly recognized as impossible. If the core European nations cannot coordinate effectively, what can we expect in dealings with China, Russia and other countries that have less of a common background and understanding?

In the euro zone, we are seeing two refusals to cooperate: Germany won’t renew financial pledges to Greece without Greek compliance on previous agreements, and Greece doesn’t want Germany to control its national budget. Both seem reasonable positions, and maybe they are, but reasonable positions can apparently destroy an international agreement rather easily.
