The United Kingdom’s exit from the European Union (EU) creates new opportunities for Europeans to unite around a common vision. The British played an important role in Europe both as a common market and as a political union. The challenge for the remaining member states will be to adapt to Great Britain’s absence. Last autumn, French President Emmanuel Macron launched an ambitious raft of proposals for reenergizing the European project. More recently, German Chancellor Angela Merkel forged a grand-coalition government with a different pro-European agenda. Macron’s vision is more centralist and involves more institutionalized solidarity; Merkel’s vision is more intergovernmental and places more emphasis on political responsibility at the national level. The success of either approach will depend upon how other European member states respond to the call for unity. The next Italian government will play a critical role.
