Iran’s new president, Hassan Rouhani, is marking the end of his first year in office. He has made a resolution of the nuclear issue and the lifting of sanctions against Iran the center-piece of a broader strategy. He hopes a breakthrough here will open the door for a revival of the Iranian economy, the reintegration of Iran into the international community, a recognition of Iran’s major role in the region and perhaps the loosening up of domestic restrictions on politics and basic freedoms. But he faces formidable opposition from an entrenched ruling elite.
