The debate focused on the impacts of sanctions against companies, individuals, and countries, as well as on American citizens domestically and internationally.

Nephew also served as the lead sanctions expert for the U.S. team negotiating with Iran. From May 2011 to January 2013, Nephew served as the Director for Iran on the National Security Staff where he was responsible for managing a period of intense expansion of U.S. sanctions on Iran.

Eric Ferrari is a Sanctions Defense Attorney based in Washington, DC with over 12 years of experience in national security law, export controls, and U.S. economic sanctions.

The New Energy Stalemate in Ukraine

Tatiana Mitrova, a fellow at Columbia University’s Center on Global Energy Policy and former energy scholar at Moscow’s Russian Academy of Sciences, and Sergey Vakulenko, an oil and gas expert at Carnegie’s Russia Eurasia Center, argue that Russia and Ukraine are locked in an energy war that has become an adaptation spiral, despite growing human and economic costs and despite current US pressure on Ukraine. They observe Ukraine’s remarkable ability to withstand Russian strikes, while questioning claims that long-range Ukrainian strikes will be able to achieve game-changing damage on Russia. Ukraine and Russia have transformed the role of energy warfare in modern conflict, drawing on low costs drones but also new forms of technological resilience that are likely to make wars longer and more dangerous.
