Stuart A. Levey , the former Under Secretary for Terrorism and Financial Intelligence in the United States , believes that the 2002 Bali bombing , and the Marriott Hotel bombing were financed by smuggling $ 30,000 in cash for each attack from al-Qaeda to allied terrorists in Asia . By contrast , the 9/11 Commission estimated the September 11 attacks in 2001 cost between $ 400,000 and $ 500,000 over two years — at least some of which was deposited in foreign accounts and accessed by the plotters in the USA
