The improvement in Sino-US relations was the main factor promoting dtente between Russia and America in the years 1969-75. How far do you agree with this view?

However, alternative factors also contributed to promoting détente between Russia and America in the years 1969-75. The fear of nuclear war and the escalating cost of the arms race pushed the Superpowers into pursuing better relations. By 1969 both sides had achieved relative nuclear parity in weapons and delivery systems, nuclear war would result in Mutually Assured Destruction. The extensive treaty systems both countries held in the third world, could result in small regional conflict developing into full scale nuclear war. Whilst the cost of maintaining this ‘balance of terror’ came at great economic cost, preventing much needed social reform. In the early 1970s the USA faced double digit inflation and widespread urban rioting in 1968. In contrast, the USSR had failed in its promise to deliver high-quality consumer products and faced falling GNP growth, from 5% in 1966-70 to 3.1% in 1971-75. These factors made it clear to the respective powers that improved relations were necessary to prevent nuclear war, agree on arms limitations and improve trade agreements: President Nixon and his NSC adviser Henry Kissinger’s successful policy of linkage meant the Soviet’s would recognise both superpowers had mutual interests in the Third World and opened up badly needed US technology and investment to the Soviet economy. Whilst the signing of arms limitation treaties of SALT 1 and the subsequent ABM treaty in 1972 was possibly the high point of US-Soviet co-operation engendered by Détente.  

Furthermore, the wider international situation of war in Vietnam and the situation in Europe precipitated improved Soviet-American relations. In the USA the war-weary public demanded withdraw from Vietnam - which in 1968 had cost 16,889 American lives – pushing the administration of President Nixon to pursue better relations with Moscow; co-operation was vital to achieve a peace settlement with Hanoi. This being achieved through the policy of Linkage which recognised the Soviet sphere of influence. In return, the USSR would support American peace talks with the North Vietnamese. Furthermore, the uneasy territorial settlement of Europe created at Yalta in 1945, which had threatened possible US intervention in 1968 during the Czechoslovakian crisis meant US-Soviet co-operation was vital to ensure peace. The Helsinki Agreement of 1975 continued the policy of East-West dialogue over Europe begun by Willy Brandt’s successful policy of Ostpolitik during the late 1960s. The Soviet controlled Warsaw Pact gained official US recognition of the post-ww2 European borders, whilst the US largely unsuccessfully sought concessions over human rights issues from the USSR, which following the agreement were widely ignored.

In conclusion, détente was the result of a variety of complex factors, driven by a war-weary United States counting the human and economic cost of militaristic confrontation of Communism in Vietnam. The United States under President Nixon recognised more could be achieved through peaceful diplomacy, whilst both Superpowers recognised that détente offered the opportunity to curtail spiralling defence spending and open up trade links between the nations. The improvement in Sino-US relations added an important Chinese dimension to Cold War diplomacy, but was not the main factor promoting détente between Russia and America in the years 1969-1975.
