The world’s greatest importer and exporter, the European Union is an economic superpower with a GDP even larger than th US. It is America’s most important trading partner and a key ally on the world stage, but how much do we really know about the nature and aim of European integration? And, in an increasingly multipolar world, will it ever challenge America’s global dominance? Featuring the most up-to-date assessment of the EU, its inner workings, external relations, and likely future development, this is the perfect introduction for anyone seeking to better understand European integration and what it means for the rest of the world, including the US.
