Goodbye Britannia? The international implications of Britain's vote to leave the EU

The vote by the British people to withdrawal from the EU – also known as a “Brexit” – means both the UK and the EU now face an unprecedented challenge. Brexit could have significant implications for the EU, the ideas and structures of European integration, and European geopolitics. The UK itself faces an uncertain future. This article examines why Brexit has come to pass and explores what it could mean for the EU, European integration, and Europe’s economics and security. It argues that as with many of the other problems the EU has faced, the EU and UK will muddle through a Brexit, coping but not solving the challenges it presents.
