1. The definition of détente is the easing of hostilities or strained relations between countries. 2. A) The Cuban Missile Crisis would be an important factor in creating the détente because it showed that both countries really would go to war and it wasn’t just a random possibility. B) American involvement in the Vietnam War lead to the détente because it showed that the American method of containing communism wasn’t working and it made them reconsider their policies towards it. The war also greatly demoralized the country as it was loss for the otherwise undefeated Americans. C) The Warsaw Pact invasion of Czechoslovakia was practically the Soviet version of Vietnam; it played out differently but had the same demoralizing effect on the country. In this case the Red Army who thought they were liberating the country from a budding capitalist were shunned by the local population. This has a demoralizing effect on the USSR and showed how communism had weakened. D) At this point in the Cold War it became apparent that neither the US nor the USSR was really going to gain the upper hand. This coupled with the fact that both countries were now even in terms of military and nuclear strength and if they went to war MAD was assured; it made them both more willing to sit down at the negotiation table. E) Economic problems in both countries meant that they had to move money around in their budgets, both countries ended up moving a lot of money from their military spending elsewhere resulting in two weakened nations who were more likely to make peace with each other. F) The Sino-Soviet Split between the USSR and China, which resulted in improved relations between the US and China pushed the USSR towards détente because now the US had a powerful friend located right next to them. Since this friend could potentially attack the USSR or act as a staging ground for US attack it’s no surprise that the USSR would want to reduce some tensions to feel safer. 3. Arms Race: SALT SALT otherwise known as the Strategic Arms Limitation Act, was a treaty that essentially froze the arms race between the US and the USSR. It limited the amount of nuclear weapons and methods of delivering nuclear in both countries. Negotiations lasted between 1969 and 1971, the pace of negotiation alternated between Vienna and Helsinki. The leaders of the two countries at the time were Leonid Brezhnev and Richard Nixon. Human Rights: Helsinki Accord The Helsinki Accord was a declaration signed by the USSR, the US and a multitude of other countries. The goal of the document was to improve relations between the Communist Bloc and the West. One of main points was about respecting human rights. The declaration was signed on August 1, 1975.
