Tehran’s diplomacy has been inept, featuring charm offensives alternating with making gratuitous enemies. It has few friends in its region, beyond tiny, Christian Armenia.

Its support of President Bashir al-Assad’s regime in Syria, while understandable from a strategic point of view, has won it few friends in the region.
