After the Cold War, two European security institutions remained: the Organization for Security and Cooperation in Europe (OSCE) and the North Atlantic Treaty Organization (NATO). Both organizations—robust tankers in size and complexity—shared the goal of enhancing security on the European continent and across the transatlantic space, despite their different roles and memberships. However, after 30 years, these organizations have charted different courses when adapting to contemporary challenges. Coauthors Robin S. Quinville, Philip T. Reeker, Jason C. Moyer of the Wilson Center’s Global Europe Program examine what is working, and what needs strengthening.
