Switzerland made detailed plans to acquire and test nuclear weapons during the Cold War.[1] Less than two weeks after the nuclear bombings of Hiroshima and Nagasaki, the Swiss government started studying the possibility of building nuclear weapons, and continued its military nuclear program for 43 years until 1988.[2][3][4] It has since signed and ratified the Treaty on the Non-Proliferation of Nuclear Weapons.[5] Switzerland never possessed biological weapons, but did have a program of the Swiss Army high command to develop and test chemical weapons.
