After Iraq invades Kuwait (see November 8, 1990), Osama bin Laden, newly returned to Saudi Arabia, offers the Saudi government the use of his thousands of veteran fighters from the Afghan war to defend the country in case Iraq attacks it. The Saudi government turns him down, allowing 300,000 US soldiers on Saudi soil instead. Bin Laden is incensed and immediately goes from ally to enemy of the Saudis. [Coll, 2004, pp. 221-24, 270-71] After a slow buildup, the US invades Iraq in March 1991 and reestablishes Kuwait. [Posner, 2003, pp. 40-41] Bin Laden will soon leave Saudi Arabia ((see Summer 1991)).
