Inhalt: Europe today is deeply divided. Thirty years after the end of the Cold War and the celebratory moment when the wall came down, we are faced with a new Cold War. Russia-Western relations are arguably more dangerous than ever since the Cuban missile crisis. Diplomatic relations are frozen, sanctions installed, the old arms control treaties abandoned, and new nuclear weapons and carriers developed. EU Europe itself is divided. It is not just Brexit, marking the first real break-away from the Union, but also clashes within. From the yellow vests clashes with police in the heart of Paris, to so-called populist movements on the rise in the periphery and across the continent. The Visegrad countries (Hungary, Poland, Slovakia, Czech Republic) are regularly at odds with the EU core (Brussels and the France-Germany axis) to a degree where the idea of sanctions is invoked. The Western security framework and NATO itself appears to break down, with Turkey, the NATO member with the organisations second largest military numerically, now purchasing Russian weapon systems and seeking strategic relations in Eurasia. How did it come to this and what happened with the post-Cold War dream? And what has happened to the post world war visions of European integration and security order? What are the critical processes and events that have led us unto this path? This book aims to address and explore these historical problems.
