Adding this layer of analysis into U.S.-Iranian relations is not just historical. It provides insight into the major U.S. Cold War policy shifts that followed the Iranian Revolution—such as the Carter Doctrine and Reagan’s decision to go on the offensive against the Soviet Union. Put simply, those policies bore a direct relation to the failure of outsourcing containment in the Middle East via arms sales and security relationships with allies such as the Shah. In that sense, arming Iran was the grand test of Nixon’s idea of outsourcing containment. And it became its grand failure. When Iran descended into revolution, the very essence of U.S. policy towards the entire Gulf region imploded. The consequence was the direct application of U.S. power in the region—something that had been resisted for decades due to fears of overstretch and a reluctance to extend the definition of U.S. national interests to another theater.
Looking at the Middle East today, it seems that the loss of Iran was a game-changing event. It forced the United States to cross a line into territory which it has been unable to step back from due to the ongoing geopolitical centrality of the region.
