A recovered document from bin Laden to Taliban leader Mullah Mohammed Omar, dated October 3, 2001, read: ” ‘A U.S. campaign against Afghanistan will cause great long-term economic burdens [on the United States] which will force America, to resort to the former Soviet Union’s only option: withdrawal from Afghanistan, disintegration, and contraction.’ ”
