In December of 2014, I submitted a Mandatory Declassification Review (MDR) of NSC 10/5 related records currently held at the Harry S. Truman Presidential Library and Museum. If you’re not familiar with 10/5, here’s a brief rundown on NSC 10/5 from the Foreign Relations of the United States series volume titled Western Europe, 1964-1968:
NSC 10/5, issued in October 1951, reaffirmed the covert action mandate given in NSC 10/2 and expanded CIA’s authority over guerrilla warfare. The PSB was soon abolished by the incoming Eisenhower administration, but the expansion of CIA’s covert action writ in NSC 10/5 helped ensure that covert action would remain a major function of the Agency.
Coordination and Policy Approval of Covert Operations dated February 23, 1967 offers a more extensive view of NSC 10/5 (at Cryptome).
My MDR request was denied by NARA in late December 2015. I submitted an appeal to the National Archives and Records Administration. My appeal letter is here. Thanks goes out to National Security Archive’s Dr. William Burr for assistance.
