Canada with a friend, transiting through Ireland in the process on a charter flight through Shannon Airport. This was in direct violation of instructions from his workplace, which mandated direct flights to North America only, in case of hijacking. Upon his return he was threatened with a disciplinary tribunal, but this never happened. Political views and activities His political views had begun to change and he became critical of many policies of the Israeli government. He opposed the 1982 Lebanon War, and when he was called up to serve in that war as a reserve soldier in the Engineering Corps, he refused to perform field tasks and instead did kitchen duty. He also campaigned for equal rights for Arab Israelis. In March 1984, he formed a left-wing group called "Campus" with five Arab and four Jewish students. He became acquainted with many Arab students, including pro-PLO activists. Vanunu was also affiliated with a group called "Movement for the Advancement of Peace". He developed a particular resentment for what he viewed as the dominance of Israeli society by Ashkenazi Jews or Jews of European origin, and discrimination against Sephardi and Mizrahi Jews from the Middle East and North Africa. He felt that he was looked down on by those who ran the Dimona facility due to his Moroccan origin. According to Dr. Ze'ev Tzahor of Ben-Gurion University, "he projected a deep sense of deprivation. He assumed an Ashkenazi dominance in Israel that encompassed all social strata and an Ashkenazi consensus closing off all possibilities of advancement for Oriental Jews." According to The Jerusalem Post, Vanunu's anti-Ashkenazi feelings morphed into anti-Jewish and anti-Israeli feelings, and he became the principal advocate for Arab students on campus, arguing their case with what other Jewish students saw as irrational intensity. He became known on campus as a radical. His activities drew increasing attention from his employer. In his security file at the Negev Nuclear Research Center, it was noted that he had displayed "left-wing and pro-Arab beliefs". In May 1984, he was questioned by the head of security at Dimona and a lawyer who was possibly from Shin Bet, and was let off with a stern warning about divulging any unauthorized information. In June 1984, he was again interrogated at the facility's security office. The next month, he left for France for two weeks with a student group to meet French-Jewish students in Paris and
