Amendment to Declassification Guidance 005-97, dated 13 June 1997
Please amend the dates of the declassification of the "fact of" targeting the Soviet Union from 1945 through 1963 to read from 1939 through 1963. The date change includes the VENONA release which was inadvertently excluded in the previous declassification guidance.
