68. First of all, with regard to the question of nuclear weapons, we believe that there should be agreement to suspend nuclear tests, subject to an inspection system to ensure that the suspension of tests is really enforced. The Soviet Union agrees that there should be a suspension of tests. There is, however, a difference of opinion as to the period of the initial suspension. We have said that it should be twelve months, followed by a second period of twelve months. The Soviet Union says that it should be two or three years.
