While broadly speaking these factors are outside the area of direct military responsibility, they have a distinct and important bearing on the total Free World military posture. The problems of world wide dispersion of nuclear weapons for potential use by and support of friendly forces and the occupation of foreign bases by U.S. forces possessing a nuclear weapon capability affect not only quantitative requirements but also design features maximizing safety in handling and simplicity It is in the light of the above considerations that I find myself in general agreement with the belief of the Joint Chiefs of Staff that in its overall long range effects a test cessation will operate to the distinct disadvantage of the United States.

While the Department of Defense does not necessarily indorse limited war concepts which would place restraints on the types of nuclear weapons which may be used and the targets which may be attacked, it is my view that it would be a serious disadvantagefor the i “* Dw . far ali) we t, k ii ’
