In 1991, Bin Laden returned to his native Saudi Arabia protesting the presence of troops, and Operation Desert Storm. He was expelled from the country. In 1996 the CIA created a team to hunt Bin Laden. They were trading information with the Sudanese until, on the word of a source that was later found to be a fabricator, the CIA closed its Sudan station later that year. In 1998 Bin Laden declared war on America, and, on August 7, struck in Tanzania and Nairobi. On October 12, 2000, Al Qaeda bombed the . In 1947 when the CIA was founded, there were 200 agents in the Clandestine Service. In 2001, of the 17,000 employees in the CIA, there were 1,000 in the Clandestine Service. Of that 1,000 few accepted hardship postings. In the first days of George W. Bush's Presidency, Al Qaeda threats were ubiquitous in daily Presidential CIA briefings, but it may have become a case of the boy who cries wolf. The agency's predictions were dire, but carried little weight, and the attentions of the President, and his defense staff were elsewhere. The CIA arranged the arrests of suspected Al Qaeda members through cooperation with foreign agencies, but the CIA could not definitively say what effect these arrests had, and it could not gain hard intelligence from those captured. The President had asked the CIA if Al Qaeda could plan attacks in the US. On August 6, Bush received a daily briefing with the headline, not based on current, solid intelligence, "Al Qaeda determined to strike inside the U.S." The U.S. had been hunting Bin Laden since 1996 and had had several opportunities, but neither Clinton nor Bush had wanted to risk taking an active role in a murky assassination plot, and the perfect opportunity had never materialized for a trigger-shy DI that would have given him the reassurances he needed to take the plunge. That day, Richard A. Clarke sent National Security Advisor Condoleezza Rice warning of the risks, and decrying the inaction of the CIA.
