The revolution in shale oil production in the United States has had a major impact on global energy markets, leading to the collapse of energy prices but also limiting their vulnerability to geopolitical instability. In an email interview, Meghan L. O’Sullivan, the Jeane Kirkpatrick professor of the practice of international affairs at Harvard University’s Kennedy School, where she directs the Geopolitics of Energy Project, and the recent author of “Windfall: How the New Energy Abundance Upends Global Politics and Strengthens America’s Power,” discusses what a rebalancing of supply and demand will mean for geopolitics going forward, if a supply gap […]

As U.S. power in the region has steadily receded over the past decade, the U.K. has tried to seize influence in a part of the world it once dominated by expanding security and economic ties. In an email interview, Jane Kinninmont, a senior research fellow and deputy head of the Middle East and North Africa program at Chatham House, explains the basis for enhanced defense cooperation, […]
