The European Union could soon be a thing of the past. Xenophobia is rampant and commonly reflected in elections across the continent. Great Britain may hold a referendum on whether to abandon the union altogether. Spurred by anti-EU sentiments due to the euro crisis, national interests conflict with a shared vision for the future of Europe. Is it too late to preserve the union that generated unprecedented peace for more than half a century?

This is no mere academic question with limited importance for America and the rest of the world. In the past decade, the EU has declined from a unified global power to a fractious confederation of states with staggering unemployment resentfully seeking relief from a reluctant Germany. If the EU collapses and the former member states are transformed again from partners into rivals, the US and the world will confront the serious economic and political consequences that follow.
