There will be four Europes

"The Decade Forecast talks about four Europes that will become increasingly estranged from one another: Western Europe, Eastern Europe, Scandinavia, and the British islands. They will still have to share the same neighborhood, but they won't be as closely connected as they were before."

"The European Union might survive in some sense, but European economic, political, and military relations will be governed primarily by bilateral or limited multilateral relationships that will be small in scope and not binding," the report says. "Some states might maintain a residual membership in a highly modified European Union, but this will not define Europe."
