The controversy over Army Sgt. Bowe Bergdahl has largely obscured what should have been an important initiative by the Obama administration. The president’s trip to Poland was one more step in what is going to be the central task of U.S. foreign policy over the next decade: deterring a great power challenge. The world today — for most countries, one that is stable, peaceful and open — rests on an order built by the United States that, since 1989, has not been challenged by any other major player. How to ensure that these conditions continue, even as new powers — such as China — rise and old ones — such as Russia — flex their muscles? (…) Today’s task is far more complicated. In World War II and the Cold War, the United States was trying to defeat entirely the great powers it was arrayed against. In the Cold War, the object of containment — as George Kennan argued from the start — was to constrain the Soviet Union such that communism would collapse under its own contradictions. The goal today is to deter China from expanding while also attempting to integrate it into the global order. Even with Russia, the goal is not to force the collapse of the regime (which would not be replaced by a pro-Western liberal democracy) but rather to deter Moscow’s aggressive instincts and hope that it will evolve along a more cooperative line.
