There were a total of four detente events during the cold war between soviet russia and the US. The first being the Nuclear non proliferation treaty. This was made to limit the spread of nuclear weapons. However, China and France do not sign the treaty because they had a high potential to acquire Nuclear technology. The second was "Ostpolitik" or in english, "East Politics". West German leader Willy Brandt wanted to make amends between the two German nations and forget about everything that happened. This was a sign of peace between democracy and communism. The third was the Helsinki accords in 1975. A number of countries met in Finland to discuss the following: Accept european frontiers, To respect human rights, And to make easier the movement across borders for people. The fourth was Strategic Arms Limitation Talks or (SALT). These were peaceful talks between Russian and the US. The first agreement was to limit ICBM's. This was then followed by the attempt to solidate nuclear parity. This was then halted due to the soviet invasion of Afghanistan. Ronald Reagan ended the detente's in 1980. I think that the act of "Ostpolitik" had the most success because it opened the possibility for communism and democracy to unite and end this world wide phenomenon.
