"This directive re-establishes the DoD policy that the Department of Defense shall support the national security of the United States by maintaining an effective nuclear deterrent while protecting public health, safety, and the environment. Nuclear weapons require special consideration because of their policy implications and military importance, their destructive power, and the political consequences of an accident or an unauthorized act. The safety, security, control, and effectiveness of nuclear weapons are of paramount importance to the security of the United States. Nuclear weapons shall not be subject to loss, theft, sabotage, unauthorized use, unauthorized destruction, unauthorized disablement, jettison, or accidental damage. Only those personnel who have demonstrated the highest degree of individual reliability for allegiance, trustworthiness, conduct, behavior, and responsibility shall be allowed to perform duties associated with nuclear weapons, and they shall be evaluated continuously for adherence to PRP standards."
