All eyes are on Russia and its hold on the Crimea. Angela E. Stent discusses U.S.-Russian relations since the Soviet collapse and on the challenges ahead. She served as an adviser on Russia under Bill Clinton and George W. Bush, argues that the same contentious issues—terrorism, missile defense, Iran, nuclear proliferation, Afghanistan, the former Soviet space, the greater Middle East—have been in every president's inbox, Democrat and Republican alike, since the collapse of the USSR. In The Limits of Partnerships: U.S.-Russian Relations in the Twenty-first Century she explores Russia's relationship with the Ukrains, and the future of U.S.-Russian relations.
