Detente bala.''
'''Détente''' is a
French term, meaning a relaxing or easing; the term has been used in international politics since the early 1970s. Generally, it may be applied to any international situation where previously hostile nations not involved in an open war de-escalate tensions through diplomacy and confidence building measures. However, it is primarily used in reference to the general reduction in the tension between the
Soviet Union and the
United States and a thawing of the
Cold War, occurring from the late
1960s until the start of the 1980s. In Russian, détente was known as "''razryadka''" (разрядка).
Causes
The two sides in the Cold War, the
NATO powers and the
Warsaw Pact, both had pressing reasons to seek relaxation in tensions.
Leonid Brezhnev and the rest of the Soviet leadership felt that the economic burden of the
nuclear arms race was unsustainable. The American economy was also in financial trouble as the
Vietnam War drained government finances at the same time as
Lyndon Johnson (and to a lesser extent,
Richard Nixon) sought to expand the government
welfare state.
In Europe, the
Ostpolitik of
Willy Brandt was decreasing tensions; the Soviets hoped that with Détente, more trade with Western Europe would be possible. Soviet thinkers also felt that a less aggressive policy could potentially detach the Western Europeans from their American ally.
Worsening relations with the
People's Republic of China, leading to the
Sino-Soviet Split, had caused great concern in the Soviet Union. The leadership feared the potential of a Sino-American alliance against them and believed it necessary to improve relations with the United States. Improved relations with China had already thawed the general American view of
communism.
Rough parity had been achieved in stockpiling nuclear weapons with a clear capability of
mutually assured destruction (MAD). There was also the realization that the "relative gains" theory as to the predictable consequences of war might no longer be appropriate. A "sensible middle ground" was the goal.

Soviet poster, "peace" in both Russian and English. The end of Russian "мир" and the English "peace" are combined. "P" is pronounced like the Latin letter "R" in Russian, thus мир is pronounced "mir".
Brezhnev and Nixon each hoped improved relations would boost their domestic popularity and secure their power.
Several anti-nuclear movements supported détente.
Summits and Treaties
The most obvious manifestation of Détente was the series of summits held between the leaders of the two superpowers and the treaties that resulted from these meetings. Earlier in the 1960s, before Détente, the
Partial Test Ban Treaty had been signed in 1963. Later in the decade, the
Nuclear Non-Proliferation Treaty and
Outer Space Treaty were two of the first building blocks of Détente. However, these early treaties did little to curb the superpowers' abilities, and served primarily to limit the nuclear ambitions of
third parties that could endanger both superpowers.
The most important treaties were not developed until the advent of the
Nixon Administration, which came into office in 1969. The Political Consultative Committee of the
Warsaw Pact sent an offer to the West, urging to hold a summit on "security and cooperation in Europe". The West agreed and
talks began towards actual limits in the nuclear capabilities of the two superpowers. This ultimately led to the signing of the
SALT I treaty in 1972. This treaty limited each power's nuclear arsenals, though it was quickly rendered out-of-date as a result of the development of
MIRVs. In the same year that SALT I was signed, the
Biological Weapons Convention and the
Anti-Ballistic Missile Treaty were also concluded. Talks on
SALT II also began in 1972.
In 1975, the
Conference on Security and Cooperation in Europe met and produced the
Helsinki Accords, a wide ranging series of agreements on economic, political, and
human rights issues. In July of the same year, the
Apollo-Soyuz Test Project became the first international space mission, with three American astronauts and two Russian cosmonauts docking their spacecraft and conducting joint experiments. This mission had been proceded by five years of political negotiation and technical co-operation, including exchanges of US and Russian engineers between the two countries' space centers.
Trade relations between the two blocs increased substantially during the era of detente. Most significant were the vast shipments of
grain that were sent from the West to the Soviet Union each year, which helped make up for the failure of
kolkhoz, Soviet collectivized agriculture.
At the same time, the
Jackson-Vanik amendment, signed into
law by
Gerald Ford on
January 3,
1975, after a
unanimous vote by both houses of the
United States Congress, was designed to leverage trade relations between the U.S. and the USSR, making them dependent upon improvements of
human rights within the Soviet Union.
Continued Conflicts
Despite the growing amicability, heated competition continued between the two superpowers, especially in the
Third World. Wars in
South Asia in 1971 and the
Middle East in 1973 saw the superpowers back their sides with material and diplomatic support. In
Latin America the United States continued to block any leftward shift in the region with military coups. For much of the Détente period, the
Vietnam War continued to rage. Neither side trusted the other fully and the potential for
nuclear war remained. Each side continued to have thousands of
intercontinental ballistic missiles (ICBMs) pointed at the other’s cities, submarines in the oceans of the world, and forces guarding disputed borders in
Korea and
Europe. The espionage war continued unabated as
defectors,
reconnaissance satellites, and signal interceptions were still a priority for both sides.
End of Détente
Détente began to unravel in 1979 due to a series of events. The
Iranian Revolution and the subsequent
hostage crisis embarrassed the United States and led much of the American public to believe their nation had lost its international power and prestige.
The
Soviets invasion of Afghanistan to shore up a struggling allied regime led to harsh criticisms in the west and a boycott of the
1980 Summer Olympics, which were to be held in
Moscow. American President
Jimmy Carter boosted the U.S.
defense budget and began financially aiding the
President of Pakistan General
Muhammad Zia-ul-Haq heavily, who would in turn subsidize the anti-Soviet
Mujahideen fighters in the region.
The
1980 American presidential election saw
Ronald Reagan elected on a platform opposed to the concessions of Détente. Negotiations on
SALT II were abandoned.
