And then there are the reported terms of the deal, which amount to an abject surrender on the part of the president. First, there will be big spending cuts, with no increase in revenue. Then a panel will make recommendations for further deficit reduction — and if these recommendations aren’t accepted, there will be more spending cuts.

Republicans will supposedly have an incentive to make concessions the next time around, because defense spending will be among the areas cut. But the G.O.P. has just demonstrated its willingness to risk financial collapse unless it gets everything its most extreme members want. Why expect it to be more reasonable in the next round?

In fact, Republicans will surely be emboldened by the way Mr. Obama keeps folding in the face of their threats. He surrendered last December, extending all the Bush tax cuts; he surrendered in the spring when they threatened to shut down the government; and he has now surrendered on a grand scale to raw extortion over the debt ceiling. Maybe it’s just me, but I see a pattern here.

Did the president have any alternative this time around? Yes.
