SALT 1 limited the production of strategic ballistic weapons (short-range, lightweight missiles) and intercontinental ballistic weapons (ICBMs), and did not allow for the addition of new nuclear missile launchers.
The Helsinki Agreements were signed in Helsinki, Finland, in 1975, by all European countries except Albania and Andorra, as well as the USA, the Soviet Union and Canada.
By the mid 1970s, nuclear weapons were becoming increasingly expensive, and the Soviet Union found it increasingly difficult to keep up in the arms race.
Gorbachev introduced perestroika (structuring) and glasnost (openness), which meant new ways of doing things and more openness for people to express their thoughts.
The SALT 2 Treaty placed limits on the number of anti-ballistic missiles (ABMS), intercontinental ballistic weapons (ICBMS), nuclear weapons (SLBMs) and long-range bombers each side had, reducing the possibility of nuclear war by ensuring that neither side had a first strike capacity.
Attempts to reduce tension between the USA and the Soviet Union had been made, but Ronald Reagan, who became US president in 1981, made no efforts to restart détente.
