Faute de mieux. That means “for want of something better” in Secretary of State John Kerry’s second language. It’s also the best case made by its journalistic defenders for approval of the nuclear weapons deal Kerry negotiated with Iran. Or to be more exact, for rallying 34 votes in the Senate or 146 votes in the House to uphold a presidential veto of a congressional vote to disapprove.

It’s a measure of the weakness of the deal that such a grudging argument is needed to rally such an unimpressive proportion of members of Congress.
