When he visits Strasbourg, France, this week to participate in festivities marking Nato's 60th anniversary, President Barack Obama should deliver a valedictory address, announcing his intention to withdraw the United States from the alliance. The US has done its job. It's time for Europe to assume full responsibility for its own security, freeing the US to attend to more urgent priorities.
The creation of the North Atlantic Treaty Organisation in 1949 remains a singular example of enlightened statecraft. With Europe's democracies still suffering from the ravages of the second world war, and fearing the threat posed by Stalinist Russia, the US abandoned its aversion to "entangling alliances" and committed itself to Europe's defence. General Dwight Eisenhower came out of retirement to serve as Nato's first military chief. As US forces arrived to take up their stations, the alliance soon found its footing. In its heyday, Nato possessed formidable capabilities and real (if never fully tested) cohesion. Its safety ensured, western Europe prospered and remained at peace.
Over time, the Soviet threat diminished and eventually disappeared. Since then, however, an alliance once regarded as the most successful in all of history has lost its way.
When the end of the cold war left Russia temporarily weakened, the United States and its allies wasted no time in exploiting that weakness. Nato pressed eastward, incorporating into its ranks nations that had previously formed part of the Soviet empire and of the Soviet Union itself. American policy-makers urged the alliance to expand its reach, abandoning its defensive posture to become an instrument of intervention. According to the conventional wisdom of the 1990s, Nato needed to go "out of area" or it would surely go "out of business".
