"Think about countries like Britain, Japan and the United States, which have large debts and deficits yet remain able to borrow at low interest rates. What’s their secret? The answer, in large part, is that they retain their own currencies, and investors know that in a pinch they could finance their deficits by printing more of those currencies. If the European Central Bank were to similarly stand behind European debts, the crisis would ease dramatically."
