Outline of the Cold War
End of the Cold War – While many observers state the 1989 Malta Summit was the end of the Cold War, it was December 1991 before the Presidents of the United States and the Soviet Union formally recognised the conflict's end, with the Soviet Union also being dissolved at that time. Some key events leading up to the end include:
Reagan Doctrine
Among others, Margaret Thatcher, Prime Minister of the United Kingdom from 1979 to 1990, has credited the Reagan Doctrine with aiding the end of the Cold War. In December 1997, Thatcher said that the Reagan Doctrine "proclaimed that the truce with communism was over. The West would henceforth regard no area of the world as destined to forego its liberty simply because the Soviets claimed it to be within their sphere of influence. We would fight a battle of ideas against communism, and we would give material support to those who fought to recover their nations from tyranny".
