Project SHAMROCK and MINARET — NSA mass surveillance

Project SHAMROCK began in August 1945, days after the end of World War II. The Army Signal Security Agency, predecessor to the NSA, approached the three major international telegraph companies operating in the United States — Western Union, RCA Global, and ITT World Communications — and asked them to hand over copies of every international telegram passing through their systems. The companies agreed. The arrangement continued for thirty years.

By the time the Church Committee uncovered the program in 1975, NSA analysts were processing approximately 150,000 telegrams per month. The messages of American citizens were collected without warrants, without judicial oversight, and without the knowledge of Congress. Senator Frank Church called it probably the largest government interception program affecting Americans ever undertaken.

Project MINARET was the operational component. Where SHAMROCK collected the raw traffic, MINARET was the targeting mechanism. Beginning in the early 1960s, the NSA began maintaining watch lists of names. American citizens whose names appeared in those lists had their international communications flagged, extracted, and reported to other government agencies. The watch lists were assembled from names submitted by the FBI, CIA, Secret Service, and Defense Intelligence Agency. They included civil rights leaders, anti-Vietnam War activists, journalists, and members of Congress. NSA Director Lew Allen testified that the cumulative total across all lists reached approximately 1,650 U.S. names during the program's operation from 1967 to 1973.

The watch list targeted people for the content of their political beliefs. Jane Fonda was on it. Joan Baez was on it. Dr. Martin Luther King Jr. was on it. So were members of the Church Committee itself, including Senator Frank Church and Senator Walter Mondale.

The NSA terminated the MINARET watch list activity in 1973 after Attorney General Elliot Richardson raised questions about its legality. SHAMROCK was terminated in May 1975 after the Church Committee began its inquiry. The Church Committee voted to declassify the existence of SHAMROCK over the objection of President Ford, the only time a congressional committee has voted to override a presidential classification objection.

Neither program had ever been authorized by statute. No court had reviewed them. No warrant had been obtained for any of the intercepts. The legal basis, to the extent one was claimed at all, was a broad interpretation of the President's constitutional authority in foreign intelligence matters. NSA Director Allen testified before the Committee that some of the activity was, in his view, not authorized by law or constitutional authority and clearly prohibited.

The programs were the direct predecessors of what Edward Snowden revealed in 2013. PRISM and bulk telephone metadata collection operated on the same institutional logic: that the NSA could collect first and ask legal questions later, or not at all. The Church Committee created the Foreign Intelligence Surveillance Act in 1978 specifically to prevent SHAMROCK and MINARET from happening again.

The Colonial Authority's mesh program in The Interference operates on a principle the NSA demonstrated was viable thirty years before the novel is set. Collect everything. Sort it later. Never ask for permission. SHAMROCK ran for thirty years without a warrant, without a statute, without the knowledge of Congress. MINARET built watch lists of Americans based on their political beliefs and distributed reports on their private communications to six government agencies. The Church Committee called it the largest governmental interception program affecting Americans ever undertaken. The Interference series asks what that institutional capacity becomes when the communications being intercepted are not telegrams but thoughts.
