Dossiers
Pieces that span agencies or countries — single operations told in depth, scandals reconstructed from primary documents, thematic surveys.
Counter-intelligence & failures
Counter-intelligence work produces a different kind of public record — typically a partial one, since active CI operations remain closed and only completed cases tend to be declassified. The Cambridge Five — Burgess, Maclean, Philby, Blunt, and Cairncross — is the founding case of postwar Anglo-American counter-intelligence and remains one of the most damaging penetrations of a Western service ever documented. The Mitrokhin Archive, the unprecedented exfiltration of KGB First Chief Directorate files by an archivist who defected to SIS in 1992, supplies the largest body of cross-confirming detail on Soviet active-measures and HUMINT operations across the Cold War. The October 7 Warning Failure dossier examines the institutional and political conditions under which Israeli intelligence assessed the conception of Hamas as deterred — a case still subject to ongoing inquiry but with substantial early reporting on the warning record.
The 7 October 2023 Warning Failure
The intelligence failure of the Israeli services to warn of the Hamas-led attack of 7 October 2023, characterised by the Director of Military Intelligence and the head of Mossad as the most consequential failure of their careers.
The 2003 Iraq WMD Intelligence Failure
The 2002–2003 US intelligence-community assessment of Iraqi weapons-of-mass-destruction programs that supplied the public case for the March 2003 invasion. Three principal failure modes — Curveball human-source reporting, the aluminum-tubes assessment, and the Niger-yellowcake forgery — converged in the October 2002 National Intelligence Estimate and the 5 February 2003 Powell UN Security Council presentation, and were documented as system-wide failures by the 2004 Senate Intelligence Committee Report and the 2005 Robb-Silberman Commission.
The Mitrokhin Archive
The archive of approximately 25,000 pages of handwritten notes copied by Vasili Nikitich Mitrokhin from the operational files of the KGB First Chief Directorate between 1972 and 1984, smuggled out of the Russian Federation following his defection to the British Secret Intelligence Service through Latvia in November 1992, and published in declassified form in two volumes co-authored with the Cambridge historian Christopher Andrew (1999 and 2005). The archive identified Soviet intelligence agents, operations, and assets across multiple Western jurisdictions and produced a series of subsequent prosecutions, public unmaskings, and parliamentary inquiries.
The Cambridge Five
The five Soviet agents — Kim Philby, Donald Maclean, Guy Burgess, Anthony Blunt, and John Cairncross — recruited at the University of Cambridge in the 1930s who became the most consequential foreign penetration of British intelligence in the twentieth century.
How dossiers differ from agency pages
An agency page sits in one country and covers one service — its history, statutory basis, role, and the public record of its operations. A dossier crosses those boundaries. A dossier picks up an operation, a scandal, or a thematic question and follows it across whichever services and states are implicated, footnoted to primary documents and the most defensible secondary record.
The Salisbury attack is a dossier rather than an agency entry because it implicates the GRU, MI5, the SIS, the Metropolitan Police, the OPCW, and the parallel Czech investigation into Vrbětice — no single agency page can carry it. The Snowden disclosures are a dossier because they involve the NSA, GCHQ, CSE, ASD, GCSB, the partner services that received the product, the journalism that processed the archive, and the long arc of post-disclosure legal and policy change. MKULTRA is a dossier because the operation was institutional in a way that has now been substantially documented by the Senate, the Rockefeller Commission, the Church Committee, and successive declassifications.
Coverage here is editorial: dossiers are written when there is a coherent public-record account that can be reconstructed at depth. The list grows as new dossiers are written and as additional declassifications expand what can responsibly be said about cases that remain partly closed.
