When the cold war ended 25 years ago, Europe emerged as prosperous, democratic, united and peaceful. Today, however, it faces interlocking crises that threaten to undermine the continent’s economy and weaken the EU.

This has significant implications for the US and for its next president. Europe remains America’s largest trade partner and investor, and 25 European nations are members of Nato, its most important military alliance.
