During the 21st Congress of the Women’s International League for Peace and Freedom, 19-23 August 1980 in Hamden, Connecticut, WILPF asked all Sections:
- to take every opportunity to publicise the treaty and oppose the development and use of nuclear and other weapons systems in outer space,
- to approach the U.N. Environment Program, Nairobi, for information on any steps being taken through the program by governments or NGOs to prevent the use of nuclear power sources such as radioisotopes and nuclear reactors, expressing our concern about such use and the development of nuclear and other weapons in outer space.
