After the Second World War the USA and the USSR began an arms race, both developing missiles which could carry nuclear war heads into enemy territory
Scientists continued to develop weapons and soon both countries had enough nuclear weapons to completely destroy their rivals, this was known as Mutually Assured Destruction or MAD
During the late 1960s and 1970s, Russian and American leaders tried to ease the tensions in their relationship
Razryadka
The Russian term for détente
The Cuban Missile Crisis of 1962 brought the world to the brink of a nuclear holocaust
Consequences of the Cuban Missile Crisis
1. Hot-Line set up between the Kremlin and the White House
2. Test Ban Treaty signed to stop nuclear tests above ground
The 1967 Outer Space Treaty stopped the arms race spreading to outer space as it pledged that no nuclear weapons would be placed in space by either superpower
The 1968 Nuclear Non-Proliferation Treaty agreed that neither superpower would supply nuclear weapons to other states or help other states to develop nuclear weapons
Richard Nixon
Became President of the USA in 1968 and had promised to end the war in Vietnam
The Soviet Union was facing economic problems and wanted to cut spending on weapons and devote more resources to improving living standards and updating the economy
By the late 1960s, both Superpowers had spent huge amounts on the arms race and were looking for ways to reduce spending
The result of Soviet spending on arms was that by the early 1970s the USSR had a distinct advantage in ICBMs and SLBMs
SALT 1
The Strategic Arms Limitation Treaty signed in 1972 that imposed limits on the nuclear capability of Russia and the USA
SALT 1 was significant because it was the first agreement between the superpowers that successfully limited the number of nuclear weapons they held
SALT 1 showed that détente had created an environment in which the two sides could co-operate on important issues
Weaknesses of SALT I
Unrealistic to expect that a piece of paper would prevent nuclear war from breaking out
Did not limit strategic bombers and number of bombs
Did not cover new technology such as MIRV
In 1974 negotiations for SALT 2 begun
Helsinki Accords 1975
Stabilised the situation in Europe by agreeing greater co-operation between the superpowers and their European allies in terms of trade and fighting international terrorism
The Helsinki Accords were the high point of detente as they agreed on Human Rights, security and co-operation
The Apollo-Soyuz mission 1975 was a joint space mission in which an American Apollo spacecraft and a Russian Soyuz spacecraft docked high about the Earth
SALT II
Arms control agreement signed in 1979 that included limits on strategic nuclear delivery vehicles, MIRVs, and new types of strategic offensive arms
Even before agreement was reached on SALT II, relations between the Superpowers began to break down
In 1977 President Carter of the USA criticised the Soviet Union's human rights' record at the Belgrade conference
The USA's recognition of the People's Republic of China in December 1978 proved annoying to the Soviet Union and led them to delay the arms control process
In the late 1970s, officials in the Carter administration wanted to use arms control to curb Soviet activities in the Developing World
In November 1979 Islamic militants captured the American embassy in Tehran, which damaged relations between the superpowers
Relations between the Superpowers were damaged following revelations of a Russian combat brigade in Cuba in September 1979
Flashpoint
A place, event, or time at which violence or hostility flares up
The KabulRevolution of April1978 witnessed the dramatic overthrow of the Afghanroyalfamily and the creation of a new government, based in the Afghan capital of Kabul, which was determined 'to buildsocialism in Afghanistan'
Hafizullah Amin assassinated Taraki, and began negotiations to form an alliance with the USA
Brezhnev believed that America would allow the invasion of Afghanistan, as it had done in Czechoslovakia following the 'Prague Spring', to avoid war
The USSR was concerned that as a result of the civil war, Afghanistan would become an Islamic state and influence nearby Soviet republics to do the same
Between 25th December 1979 and 1st January 1980 more than 50,000 Soviet troops were sent to Afghanistan to restore order
The Soviet Union remained in Afghanistan for 10 years, around 1.5 million people died, including almost 15,000 Russian soldiers
The financial cost of the war was colossal and played a significant part in the bankruptcy of the Soviet Union in the 1980s
The Carter Doctrine was the US President's response to the Soviet invasion of Afghanistan, promising military aid to all countries bordering Afghanistan and the creation of a quick strike military force
Carter's action did not force Soviet troops to withdraw from Afghanistan
The Soviet invasion of Afghanistan marked the end of détente between the superpowers
