The achievement of a common Soviet-American position on the nonproliferation of nuclear weapons is of major international importance. Whether or not it leads to a treaty obtaining a large number of signatures, the two countries have now formally recognized one of their strongest common interests. What impact this will have on their ability to work together over a wider range of security problems remains to be seen and depends on many other factors. For the moment, the central question is what influence the great powers generally can exert on the non-nuclear powers to refrain from constructing nuclear forces. Once the Soviet, American and British Governments have discovered, as they will, that 125 or more governments cannot and will not bind themselves and their successors to renounce unconditionally weapons which five major powers possess, the hard struggle to resist proliferation can begin in earnest. It starts with the substantial advantage that no non-nuclear country seems at present to be close to a decision to acquire a nuclear force.
