The 21st century has witnessed a proliferation of conflicts globally with hot spots in Europe and the Middle East. The Russia-Ukraine conflict has many dimensions that are central to all key discussions at the regional and global levels. The book analyses the emergence of a new Cold War in Europe by examining the 2014 and 2022 Russia-Ukraine conflicts/wars and their impact on Russia-EU relations. The book has three focal points. First, it employs a historical lens to examine the relationship between the Soviet Union and the European Community during the Cold War and post-Cold War periods; second, it explores the historical context of Ukraine’s relationship with Russia and Europe from Kievan Rus to the present; and third, it gives an assessment of the broader geopolitical consequences of the conflict that has precipitated a new Cold War between Russia and the EU.
