Declassified NSA Documents

Some of the documents that appear for the first time in this update shed additional light on the history of NSA. They concern the NSA's participation in the space reconnaissance program (Document 3), NSA's success in deciphering Soviet communications in the 1960s (Document 4), the efficacy of NSA activities in the late mid-to-late 1960s (Document 5), and Israel's attack on the USS Liberty during the 1967 war (Document 10). Others provide new insight on NSA's assessment of key issues in the new century (Document 21, Document 23), on NSA's attempts to adapt to the changing world and communications environment, (Document 22), on the agency's regression to old policies with regard to organizational secrecy (Document 26a, Document 26b), and on NSA activities before and after the events of 9/11 (Document 25).
