EU

In the United Kingdom, backlash against workers from other countries in the European Union is growing. Any measures to limit foreign labor, however, may threaten the future of the European common market.

The recent emergence of nationalist and populist forces in eastern Europe, coupled with the rise of Russia, now threatens to derail efforts toward further EU integration, weaken NATO, erode the continent's stability, and damage U.S. interests. Washington must ensure that the region's new politics do not damage the European project, for a strong and cohesive EU is in everyone's interest.

Without the Turkish military's support, Ankara cannot comply with the reforms necessary for Turkey to join the EU. So far, the top brass have cooperated, even when reforms have curbed their power, because they have looked at EU membership as both the culmination of the country's modernization and a way to battle nagging domestic problems. But how much further will they go?

If ratified, the new EU constitution will change the way the union works. It cannot take effect unless approved by all 25 members, but in only one country -- the United Kingdom -- do polls show that a majority oppose the document. Still, a rejection there would throw Europe into a constitutional crisis. And it could ultimately harm transatlantic relations as well.
