The other day I was on a talk show where the host asked me, “Are we better off now than we were before the Arab Spring?” And I said, “Who is we?” The furious attacks on U.S. diplomatic outposts in the Middle East have left many Americans feeling that the neighborhood was a lot safer when it was patrolled by pro-American generalissimos. But for Egypt, Libya, Tunisia, and Yemen — the countries where citizens overthrew those hated rulers — the demonstrations were a sideshow, if a mortifying one. The tumult offered a forceful reminder that “good for us” is not the same as “good for them.”
