Original sentence: Following the September 11, 2001, attacks by al-Qaeda, the United States began to build up in preparation for an attack on Afghanistan (whose government was said to harbor bin Laden's organization) in response.In the weeks before they did so, the Taliban twice offered to turn over bin Laden to a neutral country for trial if the United States would provide them with evidence of bin Laden's complicity in the attacks.The American government now claims that two-thirds of the people who were top leaders of al-Qaeda in 2001 are currently in custody (including Ramzi bin al-Shibh, Khalid Sheikh Mohammed, Abu Zubaydah, Saif al Islam el Masry, and Abd al-Rahim al-Nashiri) or dead (including Mohammed Atef), though it warns the organization is not yet defeated and is still very determined to continue the fight.The Americans, perhaps feeling this would compromise their intelligence networks, refused, and soon thereafter invaded Afghanistan, deposing the Taliban government
