But as I said, the confidence fairy hasn’t shown up. Europe’s troubled debtor nations are, as we should have expected, suffering further economic decline thanks to those austerity programs, and confidence is plunging instead of rising. It’s now clear that Greece, Ireland and Portugal can’t and won’t repay their debts in full, although Spain might manage to tough it out.

Realistically, then, Europe needs to prepare for some kind of debt reduction, involving a combination of aid from stronger economies and “haircuts” imposed on private creditors, who will have to accept less than full repayment. Realism, however, appears to be in short supply.

On one side, Germany is taking a hard line against anything resembling aid to its troubled neighbors, even though one important motivation for the current rescue program was an attempt to shield German banks from losses.

On the other side, the E.C.B. is acting as if it is determined to provoke a financial crisis. It has started to raise interest rates despite the terrible state of many European economies. And E.C.B. officials have been warning against any form of debt relief — in fact, last week one member of the governing council suggested that even a mild restructuring of Greek bonds would cause the E.C.B. to stop accepting those bonds as collateral for loans to Greek banks. This amounted to a declaration that if Greece seeks debt relief, the E.C.B. will pull the plug on the Greek banking system, which is crucially dependent on those loans.

If Greek banks collapse, that might well force Greece out of the euro area — and it’s all too easy to see how it could start financial dominoes falling across much of Europe. So what is the E.C.B. thinking?

My guess is that it’s just not willing to face up to the failure of its fantasies. And if this sounds incredibly foolish, well, who ever said that wisdom rules the world?
