Cold Wars

The last United States helicopters saved Americans from Saigon after South Vietnam collapsed.

During 1960s and 1970s, the USSR & United States suffered to cop up with bad foreign relations. Japan & Western Europe recovered from effects of World War and started developing economically during 1950s & 1960s. As the consequence of oil crisis in 1973, organizations like OPEC were formed which supported weak countries to sustain the pressure from powerful countries. Moscow had to suffer from internal problems of economy.

The USSR & United States were suffering in establishing their superiority again in their own colonies. Lyndon b. Johnson, the president stationed 22000 armed forces in Dominican Republic, fearing from revolution of Cuban style in Latin America. In 1968, the Soviet thrashed the Prague Spring Reform Movement from threat of being thrown out of Czechoslovakia.

US provided continued support to supporting countries but it proved costly for US. Johnson landed 575000 armed forces in south east Asia to fight against the National Front for the Liberation of South Vietnam but they lost to one of the weakest countries. While Brezhnev was trying to revive the economy of Soviet Nation suffering from huge defense expenditure. Later Henry Kissinger proclaimed their joint approach with China.   

Though United States & USSR had indirect conflicts in 1960s & 1970s, but still tensions were released as the détente period started. The Chinese tried to improve relations with United States to overpower USSR. In 1972, Nixon met Chou En-Lai & Mao Zedong in Beijing. The talk between Nixon & Brezhnev in Washington was a milestone in the period of détente.  

In June, Kissinger & Nixon met with the leaders of Soviet Union to implement first Strategic Arms Limitation Talks, which was meant to reduce the production of expensive arms & destructive nuclear bombs. The superpowers decided to develop economic collaboration. It was similar to "Ostpolitik" of Willy Brandt, the West German Chancellor.
