In 1957, Senator
Lyndon B. Johnson asked Vance to leave Wall Street to work for the
United States Senate Committee on Armed Services, where he helped draft the
National Aeronautics and Space Act, leading to the
creation of NASA. In 1968, Johnson sent him to
South Korea to deal with the hostage situation. Vance returned to his law practice at
Simpson Thacher & Bartlett in 1980, but was repeatedly called back to public service throughout the 1980s and 1990s, participating in diplomatic missions to
Bosnia,
Croatia, and
South Africa. Vance helped negotiate the dispute over the
Nagorno-Karabakh region. Vance played an integral role as the administration negotiated the
Panama Canal Treaties, along with peace talks in
Rhodesia,
Namibia and
South Africa. He worked closely with Israeli Ministers
Moshe Dayan and
Ezer Weizman to secure the
Camp David Accords in 1978. Vance insisted that the President make
Paul Warnke Director of the
Arms Control and Disarmament Agency, over strong opposition by Senator
Henry M. Jackson. In June 1979, President Carter and Soviet General Secretary
Leonid Brezhnev signed the treaty in Vienna's
Hofburg Imperial Palace, in front of the international press, but the Senate ultimately did not ratify it. After the
Soviet invasion of Afghanistan on December 27, 1979, Vance's opposition to what he had called "visceral anti-Sovietism" led to a rapid reduction of his stature. calling Brzezinski "evil". The only secretaries of State who had previously resigned in protest were
Lewis Cass, who resigned in the buildup to the Civil War, and
William Jennings Bryan, who resigned in the buildup to World War I. President Carter aborted the operation after only five of the eight helicopters he had sent into the
Dasht-e Kavir desert arrived in operational condition. As U.S. forces prepared to depart from the staging area, a helicopter collided with a transport plane, causing a fire that killed eight servicemen. ==Later career in law and as special envoy==
