13 April 1975, was the backdrop against which the Syrian military presence in Lebanon was established. The Middle East's geopolitical landscape was reshaped by the conflicts and wars of June 1967 and October 1973. Israel's resounding win in 1967, compounded by its annexation of the Sinai Peninsula, East Jerusalem and the West Bank, the Gaza Strip, and the Golan Heights, dealt a catastrophic blow to Egyptian President Gamal Abdel Nasser and the pan-Arabist ideology.
