Book excerpt: During the Cold War, the two global superpowers were able to come together to resolve many issues of transparency and common challenges, leading to a change in European and global security. The OSCE covered the area formerly occupied by NATO and the Warsaw Pact, championing the Helsinki Final Act, which became a key international instrument to encourage peace and security. Following the end of the Cold War, the OSCE became a key institution positioned between the European Union and NATO, focusing on furthering democracy, protecting human and minority rights, and encouraging military reform in a drastically dynamic region. David J. Galbreath sheds light on an institution that changed the face of global security during the Cold War and championed the rise of democratization in Central and Eastern Europe as well as the former Soviet republics following the collapse of the Soviet Union.
