The North Atlantic Treaty Organization turns 70 in April. To discuss challenges to and opportunities for the alliance as it enters its eighth decade, this episode features a discussion among a group of leading Brookings experts: John Allen, president of the Brookings Institution; Constanze Stelzenmüller, the Robert Bosch Senior Fellow in the Center on the United States and Europe at Brookings; and Michael O'Hanlon, a senior fellow and director of research in the Foreign Policy Program at Brookings. Also in this episode, Samantha Gross, fellow in the Foreign Policy program's Energy Security and Climate Initiative, and Suzanne Maloney, deputy director of Foreign Policy and senior fellow in the Center for Middle East Policy, discuss top geopolitical issues, including Russia's role in Syria, the broader Middle East, and how Iran might use oil prices to respond to continued pressure from the Trump administration. Gross and Maloney had this conversation while they were at CERA Week in Houston, Texas.
