He's right about one thing: Getting Greece's economy back to sustainable growth requires debt relief. But this might be hard to arrange – unless Germany's government decides to be less responsive to its voters, Bloomberg wrote.

Greece's public debt stands at roughly 180 percent of gross domestic product. That's insupportable, even with the more generous terms (low interest rates and more time to pay back the borrowing) now in place. The economic case for further debt relief isn't really in doubt.

The International Monetary Fund, no bleeding heart in matters of fiscal rectitude, has for many months been urging EU governments to act. "It cannot be assumed that Greece can simply grow out of its debt problem," officials noted in a recent appraisal. Further debt relief will be needed, "going well beyond what is currently under consideration."

Obama has backed this message before, and he said it again this week. He praised the efforts Greece has already made to improve its public finances and get its economy working more efficiently. For sure, there's more to do in that respect, as the IMF has emphasized, but Greece can't get from here to a durable recovery without the help of the EU.


Unfortunately, Europe's governments aren't yet willing. With elections in France and Germany approaching, and patience with Greece's endless difficulties running low, they're reluctant to force explicit losses on to their taxpayers. One day they might have to bow to the inevitable, but the longer the inevitable can be delayed, the better.

A continued policy of extend and pretend will cripple Greece's prospects, and if that happens, the economic and political costs won't be confined to Greece.

In this case, Europe's leaders need to respond a bit less to their voters' doubts, and to lead a bit more. There is a strong case for enlightened, self-interested solidarity. Maybe Obama's nudge will get results.
