145. Letter From Secretary of Defense McNamara to Secretary of State Rusk 1
The draft states that the President does not now expect to authorize first use of lethal CB weapons. With respect to incapacitants, it reflects the actual situation as it now exists by stating that the President may authorize their use in certain situations of national urgency. In my view, we should keep this option open until we have better information concerning specific incapacitating agents, their military effectiveness, and the political consequences of their use. Accordingly, I have asked the members of my staff to conduct a study on the role of incapacitating agents. The results of this study will be reflected in next year’s Draft Memorandum for the President on Theater Nuclear Warfare. In the meantime, I believe policy guidelines such as those in the attached draft NSAM would be appropriate and desirable.
I share your interest in reaching an early joint position which we can recommend to the President. I would be happy to discuss the draft policy with you at your convenience, if you wish.
