The Musandam Peninsula is an exclave of Oman separated from the rest of the sultanate by a strip of UAE territory. It juts northward into the Gulf, forming the southern jaw of the Strait of Hormuz. Iran’s coastline forms the northern jaw. Between them is the corridor through which the global oil trade flows. Oman is the only country in the world that shares a maritime border with Iran along the strait, and this geographic fact has given the sultanate a diplomatic role that its size and military capacity would not otherwise justify.
