One of these was the Budapest Memorandum of 1994, in which the Russian Federation (along with the United Kingdom and the United States) had guaranteed Ukrainian borders when Ukraine agreed to give up all nuclear weapons. In what was perhaps the greatest act of nuclear disarmament in history, Ukraine handed over some 1,300 intercontinental ballistic missiles. By invading a country that had engaged in complete nuclear disarmament, Russia offered the world the lesson that nuclear arms should be pursued.
