UN Special Sessions on Disarmament In response to the continuing arms race, the United Nations General Assembly convened its first special session on disarmament in 1978. Delegations of peace activists from around the world marched through the streets of New York City during this exceptional event. They included 500 Japanese activists seeking the abolition of nuclear weapons. Two more special sessions on disarmament were held at the United Nations in 1982 and 1988. “No more hibakusha!
