Diplomatic Sigint and the British Official Mind during the Second World War: Soviet claims on Turkey, 1940–45

Abstract

Historians of Soviet foreign policy have recently revisited the issue of Soviet claims against Turkey: a Stalinist objective during the period of the Nazi–Soviet Pact and in the immediate post-war era. Recently opened archives show that the British response to Soviet claims in 1945 was driven by comprehensive access to Turkish diplomatic correspondence. However, the British failed to recognize wartime decrypts that indicated continuity in Soviet ambitions in Turkey since 1940. This failure reflected the responsibility of the operational departments of the Foreign Office for the assessment of diplomatic Sigint, and the absence of a genuine political intelligence department with eyes for anything other than current lines of policy.
