Lead or Leave (also known as Lead... or Leave) was an American grassroots political action group from 1992 to 1995.
 Led by Rob Nelson and Jonathan Cowan, it focused on reducing the deficit and fighting for generational equity.
 Lead or Leave garnered national attention with an accountability pledge that asked the President and all members of Congress to pledge to cut the federal deficit in half in four years or leave office.
 The "mini-movement" became so prominent it was featured on 60 Minutes, Nightline, Good Morning America and The Today Show, creating a stir in "MTV-DC" during the Clinton years.
Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th President of the United States from 1969 until 1974, when he resigned from office, the only U.S. president to do so.
 He had previously served as the 36th Vice President of the United States from 1953 to 1961, and prior to that as a U.S. Representative and also Senator from California.
The 1970s proved to be a pivotal period for the anti-nuclear movement in California.
 Opposition to nuclear power in California coincided with the growth of the country's environmental movement.
 Opposition to nuclear power increased when President Richard Nixon called for the construction of 1000 nuclear plants by the year 2000.
The anti-nuclear movement in the United States consists of more than 80 anti-nuclear groups that oppose nuclear power, nuclear weapons, and/or uranium mining.
 These have included the Abalone Alliance, Clamshell Alliance, Committee for Nuclear Responsibility, Nevada Desert Experience, Nuclear Information and Resource Service, Physicians for Social Responsibility, Plowshares Movement, and Women Strike for Peace.
 The anti-nuclear movement has delayed construction or halted commitments to build some new nuclear plants, and has pressured the Nuclear Regulatory Commission to enforce and strengthen the safety regulations for nuclear power plants.

Slovenia's only nuclear power plant is the Krško Nuclear Power Plant, which went into commercial operation on January 15, 1983.
 It was built as a joint venture by Slovenia and Croatia which were at the time both part of Yugoslavia.
 The operating company Nuklearna Elektrarna Krško (NEK) remains co-owned by Slovenian and Croatian state-owned companies and provides more than one quarter of Slovenia's electrical power along with roughly a fifth of Croatia's.
 The plant is scheduled to close by 2023, and there are no plans to build further nuclear plants.
 Nonetheless, the debate on whether and when to close the Krško plant has intensified since the 2005/06 winter energy crisis.
 In May 2006 a Slovenian newspaper claimed that the government had held internal discussions on adding a new 1000MW block into Krško after 2020.
 Nuclear waste is disposed in storage facilities.
 Slovenia has left the possibility of reprocessing spent fuel open.
The Zwentendorf Nuclear Power Plant was the first commercial nuclear plant for electric power generation built in Austria, of 3 nuclear plants originally envisioned.
 Construction of the plant at Zwentendorf, Austria was finished but the plant never entered service.
 The start-up of the Zwentendorf plant, as well as the construction of the other 2 plants, was prevented by a referendum on 5 November 1978.
 A narrow majority of 50.47% voted against the start-up.
Nuclear safety in the U.S. is governed by federal regulations issued by the Nuclear Regulatory Commission (NRC).
 The NRC regulates all nuclear plants and materials in the U.S. except for of nuclear plants and materials controlled by the U.S. government, as well those powering naval vessels.
The Center for Year 2000 Strategic Stability was a joint operation of the United States and Russian Federation designed to provide mutual assurance that neither nation was launching a nuclear first strike against the other during the transition from the year 1999 to the year 2000.
 The program arose out of concerns the Year 2000 problem might generate false positives in each nation's nuclear attack early warning systems.
Weiss was born and raised in Stefling (near Nittenau), not far from Wackersdorf, where during the 1980s, the West German nuclear industry began building the nuclear reprocessing plant Wackersdorf a nuclear reprocessing plant.
 Upset by this move, Weiss took leave from his position as Professor of Inorganic Chemistry at Ludwig Maximilians University in Munich, and began making public appearances in opposition to the plant.
 Eventually the construction of Wackersdorf was stopped.
 Later, as a member of the Bavarian state government, he continued to oppose nuclear plants.
 In 2007, Professor Weiss received the Nuclear-Free Future Lifetime Achievement Award.

Question: How did the president who called for the construction of 1000 nuclear plants by the year 2000 leave office?
