ABSTRACT
During World War II, Finland’s codebreakers solved some of the cryptosystems of the Red Army, the U.S. State Department, and the Turkish Foreign Ministry, among the major targets, and cryptosystems of Romania, Brazil, and the Vatican as minor targets. But the results, though successful technically, had but little effect either upon Finland’s military tactics during her two wars with the Soviet Union-the Winter War of 1939-1940 and the Continuation War of 1941-1944-or upon her foreign policy toward the United States, which until 1944 maintained diplomatic relations with her although she was a co-belligerent of America’s enemy, Nazi Germany.
