Part of the search for a new spirituality saw the rise of popularity of new religious movements in the United States such as the so-called "New Age" movements; the Unification Church of South Korea; of "eastern" religions such as Buddhism, Taoism and Hinduism; and of various fundamentalist Protestant churches that predicated the imminence of the Apocalypse. A particular sign of the growing popularity of the latter was the best-selling 1970 book "The Late, Great Planet Earth" by an American fundamentalist minister Hal Lindsey, which warned that the Apocalypse was about to occur in the very near-future. In his book, Lindsey tied Biblical prophecies to current events; for an example, Lindsey asserted that the European Economic Community (EEC), which its proponents believed would ultimately create an "United States of Europe" would be a new "Roman empire". The economic success of the EEC, which had been founded in 1957, led to a belief by the late 1960s-early 1970s that an "United States of Europe" was a real possibility within the near-future, for which some people confirmed the accuracy of Lindsey's predications. Likewise, the fact that Soviet Union had supported Syria and Egypt in the Six Day War of 1967 and Egypt again to a much greater extent in the War of Attrition in 1969-70 was used by Lindsey to argue that the Soviet Union would one day go to war with Israel, thereby leading to a Soviet-American nuclear exchange which would be the "War of Gog and Magog" predicated in the Book of Revelation. Starting in January 1970, in response to a threat by President Gamal Abdel Nasser of Egypt to otherwise take his nation into the American sphere of influence, the Soviet leader Leonid Brezhnev had dispatched thousands of Soviet military personnel to operate SAM (surface-to-air missiles) and radar sites in Egypt together with hundreds of Red Air Force's planes, leading to a number of Soviet-Israeli clashes during the final phrase of the War of Attrition in 1970. The way in which the Soviet Union became involved in the War of Attrition seemed for some to validate Lindsey's predications that one day the Soviet Union would attack Israel.
