Swedish nuclear weapons program

After World War II, Sweden considered building nuclear weapons to defend themselves against an offensive assault from the Soviet Union. From 1945 to 1972 the government ran a clandestine nuclear weapons program under the guise of civilian defence research at the Swedish National Defence Research Institute (FOA). By the late 1950s the work had reached the point where underground testing was feasible. However, at this time the Riksdag prohibited research and development of nuclear weapons, pledging that research should be done only for the purpose of defence against nuclear attack. They reserved the right to continue development of offensive weapons in the future. In recent years declassified documents have shown that Sweden was much closer to possessing the nuclear bomb than previously thought. By 1965 most of the bomb was already built and another 6 months would have been needed to arm it, had the project been given the green light. Another two bombs would have been built shortly thereafter. The option to continue development of weapons was abandoned in 1966, and Sweden's subsequent signing of the Non-Proliferation Treaty (NPT) in 1968 began the wind-down of the program, which finally concluded in 1972. Sweden was strongly influenced to abandon its nuclear weapons program by the United States.
