The purpose of this article is, first, to analyze certain of the obstacles JL that have principally impeded progress on the subject of disarmament over the past fifteen years and more; secondly, to suggest that these difficulties may be less likely to frustrate the conclusion of limited agreements in the field of conventional weapons alone than of the more comprehensive type of agreement that has been chiefly discussed; thirdly, to try to demonstrate that, so long as comprehensive disarmament remains unattainable, progress in regard to conventional weapons is not only more easily to be achieved but more valuable than progress in other spheres; and, finally, to discuss some of the particular fields in which it might be possible to reach useful agreements within this sphere.
