Presidential Directive 59 (PD-59) was a top secret document titled "Nuclear Weapons Employment Policy" prepared by the Carter administration and dated 25 July 1980 that contained plans for carrying out an extended nuclear war.[1]
Csrter's National Security Advisor Zbigniew Brzezinski described it as an addition to National Security Decision Memorandum 242, a Nixon administration document that it superseded.[2] [3]
Parts of its contents were leaked shortly after its creation, causing a public furore about nuclear escalation.[4]
A redacted version of PD-59 has since been declassified and released publicly.
