How did president nixon differ from previous presidents in regard to his views on communism and containment

Nixon held office during the Cold War, a sustained period of geopolitical tension between the United States and the Soviet Union. Nixon's foreign policy focused on détente with the Soviet Union and China, as he sought to move away from traditional ideological conflicts and the policy of containment. Détente was designed to relax tensions with the Soviet Union, reduce nuclear arsenals, and limit military commitments.

Kennedy's strategy was to paint the Republican administration in which Nixon served as timid, indecisive, and given to poor strategizing in terms of the Cold War. Nixon, on the other hand, wanted to portray Kennedy as naive and much too willing to compromise with the Soviets and communist Chinese.

Richard Nixon changed Cold War diplomacy most notably by his efforts to open diplomatic ties between the United States and China. By doing this, he drove a wedge between China and the Soviet Union and, thereby, helped to improve relations between the US and the USSR.

He focused on détente with the People's Republic of China and the Soviet Union, easing Cold War tensions with both countries. As part of this policy, Nixon signed the Anti-Ballistic Missile Treaty and SALT I, two landmark arms control treaties with the Soviet Union.

answer:   migrations were important in the neolithic period. "two major migrations passing through southeastern europe were confirmed by the means of archaeo-genetic studies."

the first migration was the early neolithic period -- 6,000 before common era (bce) -- when the first farmers, from anatolia -- asia minor -- spread through europe. the second migration occurred during the early bronze age (3,000-2,500 bce) when the so-called "steppe population," from the eurasian steppe, replaced much of northern europe's previous population.

the first farmers of northern and western europe passed through southeastern europe with limited hunter-gatherer genetic admixture, which occurs when two or more previously isolated populations begin interbreeding. however, some groups that remained mixed extensively -- without the male-biased, hunter-gatherer admixture that prevailed later in the north and west, according to latest discoveries. southeastern europe continued to be a nexus between east and west, with intermittent genetic contact with the steppe people up to 2,000 years before the migrations that replaced much of northern europe's population.

"in some places, hunter-gatherers and incoming farmers seem to have mixed very quickly," says iain mathieson, a geneticist at the university of pennsylvania, who was first author of the paper. "but, mostly, the two groups remained isolated, at least for the first few hundred years. these hunter-gatherers had been living there for thousands of years, and it must have been quite a shock to have these new people show up -- with a completely different lifestyle and appearance."
