Selected by Choice as an Outstanding Academic Book, this notable work has now been thoroughly updated and revised to investigate the sources, manifestations, and implications of interstate and interethnic instability in post-Communist eastern Europe. Janusz Bugajski illuminates long-suppressed historical antagonisms, traces the key contemporary conflicts, and considers evolving forms of regional cooperation and European integration. Pinpointing the new actors and factors shaping eastern European developments, the author considers likely scenarios of future unrest, particularly in light of the Yugoslav wars and persistent tensions throughout the Balkans.
