background of the Six-Day War. After Neeman cleared it with Prime Minister Levi Eshkol, Teller briefed the head of the CIA's Office of Science and Technology, Carl Duckett. It took a year for Teller to convince the CIA that Israel had obtained nuclear capability; the information then went through CIA Director Richard Helms to the president at that time, Lyndon B. Johnson. Teller also persuaded them to end the American attempts to inspect the Negev Nuclear Research Center in Dimona. In 1976 Duckett testified in Congress before the Nuclear Regulatory Commission, that after receiving information from an "American scientist", he drafted a National Intelligence Estimate on Israel's nuclear capability. In the 1980s, Teller again visited Israel to advise the Israeli government on building a nuclear reactor. Three decades later, Teller confirmed that it was during his visits that he concluded that Israel was in possession of nuclear weapons. After conveying the matter to the U.S. government, Teller reportedly said: "They [Israel] have it, and they were clever enough to trust their research and not to test, they know that to test would get them into trouble." Three Mile Island Teller suffered a heart attack in 1979, and blamed it on Jane Fonda, who had starred in The China Syndrome, which depicted a fictional reactor accident and was released less than two weeks before the Three Mile Island accident. She spoke out against nuclear power while promoting the film. After the accident, Teller acted quickly to lobby in defence of nuclear energy, testifying to its safety and reliability, and soon after one flurry of activity suffered the attack. He signed a two-page-spread ad in the July 31, 1979, issue of The Washington Post with the headline "I was the only victim of Three-Mile Island". It opened with: Strategic Defense Initiative In the 1980s, Teller began a strong campaign for what was later called the Strategic Defense Initiative (SDI), derided by critics as "Star Wars", the concept of using ground and satellite-based lasers, particle beams and missiles to destroy incoming Soviet ICBMs. Teller lobbied with government agencies—and got the approval of President Ronald Reagan—for a plan to develop a system using elaborate satellites which used atomic weapons to fire X-ray lasers at incoming missiles—as part of a broader scientific research program into defenses against nuclear weapons. Scandal erupted when Teller (and his associate Lowell Wood) were accused of deliberately overselling the program
