戦略兵器制限交渉
In the 1980s, a movement for nuclear disarmament again gained strength in the light of the weapons build-up and statements of US President Ronald Reagan. Reagan had "a world free of nuclear weapons" as his personal mission, and was largely scorned for this in Europe. Reagan was able to start discussions on nuclear disarmament with Soviet Union. He changed the name "SALT" (Strategic Arms Limitation Talks) to "START" (Strategic Arms Reduction Talks).
