Cold War
Episode Nineteen
Freeze (1977–1981) Carter's ambitious proposals for total
multilateral nuclear disarmament are rejected by Brezhenv; his
championing of human rights does not win favour either. The Helsinki Accords encourage writers to establish Charter 77 in Czechoslovakia. The visit of Pope John Paul II revitalises Polish nationalism, while in the Soviet Union high profile dissidents and refuseniks
gains popular attention. The Soviets continue a conventional arms race,
draining resources from a demoralised consumer economy. SALT II is signed, to the consternation of many Europeans because of the Treaty's "double track" provisions concerning the deployment of new SS-20 and Pershing II missiles. Carter's failure to exercise American resolve and strength over the Soviet invasion of Afghanistan, the Iran hostage crisis and an oil shock ultimately costs him the 1980 elections, and the United States decisively swings to a more confrontational foreign policy under Ronald Reagan. Breznhev successfully leans on Polish leader Wojciech Jaruzelski to crack down on the Solidarity movement. Interviewees include Jeane Kirkpatrick, Lech Walesa, Václav Havel and Helmut Schmidt. The pre-credits scene shows the United States basking in confidence during its bicentennial, with the narrator noting détente would shortly be over.
