Roger Cohen: “America cannot stop the Sunni-Shia schism in the Middle East that its invasion of Iraq exacerbated. It cannot rebuild the Sykes-Picot order, or the borders that went with it. It cannot reverse its failure to prevent the worst in Syria (which will forever blot Obama’s record), nor its failure, outside Tunisia, and particularly in Egypt, to nurture the hope of the Arab spring for more representative societies freed from the paralyzing (and mutually reinforcing) confrontation of dictatorship and Islamism. It cannot prevent the violence inherent in all these developments. Nor should it hide its eyes from the fact that this violence will last a generation at least.
This is not cause for despair but reason to concentrate, fiercely, on the two attainable objectives that matter most now.’
