NATO was born of a crisis, and its trouble today results from the fact that the crisis is gone. The ruins of war have been cleared away. The drama of 1949—of a clash between Germany's conquerorshas faded. The ambition of the Soviet Union to dominate Western Europe undoubtedly still exists, but it is a passive threat, a latent threat which no longer has in it an immediacy and power sufficient to compel great measures of defense, The states of Western Europe are no longer the unconfldent nations they were in the last years of the 1940's; they no longer need rely upon the United States to defend them from the Soviet Union; and the Soviet Union is no longer quite the bizarre society it was in those years of menace.
