"His "big plan," which led to the war in Lebanon, attempted to solve the demographic problem by turning Jordan into Palestine, deporting the refugees from Lebanon, transferring them from the West Bank, and destroying the Hashemite kingdom." In the days of black September and the attempted PLO takeover of Jordan in 1970, the Labor government was in power in Israel and Sharon was a general. Syria invaded Jordan in support of various Palestinian factions there, and occupied the Jordanian city of Irbid. Thanks to Israeli air force planes flying low over the Syrian tanks, the Syrian army withdrew, and the Jordanian army's victory over the Palestinian armed factions was assured. Thanks to Israel's threat to use force, the Hashemite kingdom was saved. The Lebanese civil war was a direct result of the 1969 Cairo agreement in which Lebanon, under pressure from various Arab governments, allowed the PLO to operate militarily on its soil. That was 13 years before Sharon's debackles in Lebanon.
