NATO

The Obama administration's cancellation of a missile-defense network in Europe is not a sign of misguided weakness, but rather the result of a prudent reexamination of U.S. priorities. But what will come in its place?

Moscow and Washington are calling their recent summit a success. But to move beyond cosmetic agreements, the United States will have to think of Russia as a strategic partner and not just a negotiating one.

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.

Long the bulwark of the transatlantic security relationship, NATO now faces a threat from within Europe itself. The proposed EU constitution makes clear that the new Europe seeks to balance rather than complement U.S. power-making European political integration the greatest challenge to U.S. influence in Europe since World War II. Washington must begin to adapt accordingly.
