There may be those who wish to hear more — more promises to this group or that — more harsh rhetoric about the men in the Kremlin — more assurances of a golden future, where taxes are always low and subsidies ever high.

But peace does not rest in charters and covenants alone. It lies in the hearts and minds of all people. And if it is cast out there, then no act, no pact, no treaty, no organization can hope to preserve it without the support and the wholehearted commitment of all people.

This decision demands a major national commitment of scientific and technical manpower, materiel and facilities, and the possibility of their diversion from other important activities where they are already thinly spread. It means a degree of dedication, organization and discipline which have not always characterized our research and development efforts. It means we cannot afford undue work stoppages, inflated costs of material or talent, wasteful interagency rivalries, or a high turnover of key personnel.
