A charter member of the Arab League, Saudi Arabia has supported Palestinian rights to sovereignty, and called for withdrawal from the West Bank and other territory occupied by Israel since 1967. In 1947, Saudi Arabia was one of several Middle Eastern states that voted against in the United Nations Partition Plan for Palestine. Saudi troops were sent to fight against Israel in the 1948 and 1973 wars. The 1981 Israel operation Operation Opera, a preemptive strike on nuclear reactor purchased by Iraq from France in 1976, allegedly took place with the cooperation of Saudi Arabia, as the flight path was over Saudi territory.. In recent years Saudi Arabia has changed its viewpoint concerning the validity of negotiating with Israel, which it previously refused. It calls for Israel's withdrawal from territory occupied in June 1967. In 2002 then-Crown Prince Abdullah extended a multilateral peace proposal based on withdrawal that would follow the borders of a two-state solution. At that time, Israel did not respond to the offer. In 2007 Saudi Arabia again officially supported a peaceful resolution of the Arab–Israeli conflict in which Israel was to concede to withdraw to the borders set in the two-state solutions, which generated more official negative reactions from Israeli authorities, citing the Oslo Accords and the Saudis' deviation from those accords. At this time, no demands were made of any other party other than of Israel.
