The Liberal Core and Realist Periphery in Europe

The post-Cold War world is divided into two worlds - a liberal core and a realist periphery. The core and the periphery, however, are not permanently divided, and their interaction in Europe is particularly dynamic. In general, the core powers - led by the United States - have moved to expand their zone of peace and prosperity eastward. And while Russia should (and often says it does) feel threatened by this eastern expansion, Moscow has generally pursued a policy of integration with the West for the last decade.
