Since at least World War II, U.S. foreign policy has been shaped by the necessity of securing scarce oil supplies. And for more than 30 years, it has been shaped by a commitment to safeguard the flow of oil from the Persian Gulf. Many of the defining moments in U.S. foreign policy since then– including the Arab oil embargoes of the 1970s, the 1980s ‘tanker war’ and even the 1991 Persian Gulf War – have been shaped by this commitment, perhaps most clearly articulated by President Carter in 1980:

Let our position be absolutely clear: An attempt by any outside force to gain control of the Persian Gulf region will be regarded as an assault on the vital interests of the United States of America, and such an assault will be repelled by any means necessary, including military force.

Yet recent years have seen profound changes in the global oil market. Growth in U.S. domestic production – a result of the shale gas revolution – has returned the United States to the top of global hydrocarbon producer rankings for the first time in decades. A more general shift in production from global south to north has made the United States substantially less reliant on Middle Eastern sources of oil, and more on close neighbors like Canada.

These changes, combined with dramatic shifts in the Middle Eastern balance of power raise a key question: should the United States continue to use its military to guarantee the flow of oil from the Persian Gulf?

On February 27^th, Cato will host a book forum to discuss the recently published book Crude Strategy: Rethinking the U.S. Military Commitment to Defend Persian Gulf Oil. The book addresses many of these key questions, pulling together an interdisciplinary team of political scientists, economists, and historians to explore the links between Persian Gulf oil and U.S. national security.

The book’s essays explore key questions such as the potential economic cost of disruption in oil supply, whether disruptions can be blunted with nonmilitary tools, the potential for instability in Saudi Arabia, and the most effective U.S. military posture for the region. By clarifying the assumptions underlying the U.S. military presence in the Persian Gulf, the authors conclude that the case for revising America’s grand strategy towards the region is far stronger than is commonly assumed.

The discussion will feature the book’s editors, Charles Glaser, Professor of Political Science and Director, Institute for Security and Conflict Studies at the George Washington University and Rosemary Kelanic, Assistant Professor of Political Science, Williams College. Joining them will be Kenneth Vincent, Visiting Fellow, Institute for Security and Conflict Studies, George Washington University and John Glaser, Cato’s Associate Director of Foreign Policy Studies.

The event promises a fascinating discussion on the energy security roots of America’s foreign policy in the Middle East, and the future of the U.S. commitment to the region’s oil supplies. You can register for the event here.
