If anything has been adopted as the single, most important, immediate objective of the U.S, “Foreign Policy Establishment,” it is the conclusion, with the Soviet Union, of a treaty designed to discourage the spread of nuclear weapons to countries that do not already possess them. I use the word “discourage,” because it seems clear that the treaty itself is not intended to produce anything more than an abstention, on the part of the U.S. and the USSR, from active participation in the act of proliferation. There is to be no commitment, or so it would appear, to joint action (economic, political, or military) to prevent the spread of nuclear weapons.
