Seminars 2019


Spy flights during the cold war with Tomas Dal, Saturday 12.00-13.00.

After WWII, the Soviet Union established communist regimes throughout eastern Europe, and an ”iron curtain” stopped all further contact between the former allies, which gradually increased the need for intelligence on Soviet structure of strategic nuclear weapons.
The lecture is about the period 1945-1962, when the Cuban crisis led to the establishment of the ”red line” and spy satellites took over the information needs that existed.
The lecture also concerns Sweden’s role and what we know about the Soviet spy flights.
