March 25, 1983
Today the President issued a National Security Decision Directive addressing his intent to direct
the development of an intensive effort to define a long-term research and development program
aimed at an ultimate goal of eliminating the threat posed by nuclear ballistic missiles as announced
in his speech of March 23, 1983.
The document directs the following:
It is my policy to take every opportunity to reduce world tensions and enhance stability. Our
efforts to achieve significant reductions in strategic offensive forces and to eliminate LRINF
land-based missiles are one approach to that aim. However, it is my long-range goal to go beyond
this. I would like to decrease our reliance on the threat of retaliation by offensive nuclear weapons
and to increase the contribution of defensive systems to our security and that of our allies. To
begin to move us toward that goal, I have concluded that we should explore the possibility of
using defensive capabilities to counter the threat posed by nuclear ballistic missiles.
I direct the development of an intensive effort to define a long-term research and development
program aimed at an ultimate goal of eliminating the threat posed by nuclear ballistic missiles.
These actions will be carried out in a manner consistent with our obligations under the ABM
Treaty and recognizing the need for close consultations with our allies.
In order to provide the necessary basis for this effort, I further direct a study be completed on a
priority basis to assess the roles that ballistic missile defense could play in future security strategy
of the United States and our allies. Among other items, the study will provide guidance necessary
to develop research and development funding commitments for the FY 85 Departmental budgets
and the accompanying Five-Year Defense Program (FYDP).
The Assistant to the President for National Security Affairs is assigned the responsibility to
formulate detailed instructions for implementing this NSDD including organization, assignment of
responsibilities, and completion dates.
