We take pleasure in publishing the following study which was written in the spring of 1971. Some passages, as readers will observe, are no longer topical, such as the information given on the Conference of Government Experts, for our readers will know that, the 1971 conference is being followed by a second session from 3 May to 3 June 1972, in Geneva.
The study appeared in L'Univers politique 1970, and we express our thanks to the Editions Richelieu, Paris, for authorizing reproduction in our Review. (Ed.)
