a neutral country for trial if the US would provide evidence of bin Laden's complicity in the attacks. US President George W. Bush responded by saying: "We know he's guilty. Turn him over", and British Prime Minister Tony Blair warned the Taliban regime: "Surrender bin Laden, or surrender power." Soon thereafter the US and its allies invaded Afghanistan, and together with the Afghan Northern Alliance removed the Taliban government as part of the war in Afghanistan. As a result of the US special forces and air support for the Northern Alliance ground forces, a number of Taliban and Al-Qaeda training camps were destroyed, and much of the operating structure of Al-Qaeda is believed to have been disrupted. After being driven from their key positions in the Tora Bora area of Afghanistan, many Al-Qaeda fighters tried to regroup in the rugged Gardez region of the nation. By early 2002, Al-Qaeda had been dealt a serious blow to its operational capacity, and the Afghan invasion appeared to be a success. Nevertheless, a significant Taliban insurgency remained in Afghanistan. Debate continued regarding the nature of Al-Qaeda's role in the 9/11 attacks. The US State Department released a videotape showing bin Laden speaking with a small group of associates somewhere in Afghanistan shortly before the Taliban was removed from power. Although its authenticity has been questioned by a couple of people, the tape definitively implicates bin Laden and Al-Qaeda in the September 11 attacks. The tape was aired on many television channels, with an accompanying English translation provided by the US Defense Department. In September 2004, the 9/11 Commission officially concluded that the attacks were conceived and implemented by Al-Qaeda operatives. In October 2004, bin Laden appeared to claim responsibility for the attacks in a videotape released through Al Jazeera, saying he was inspired by Israeli attacks on high-rises in the 1982 invasion of Lebanon: "As I looked at those demolished towers in Lebanon, it entered my mind that we should punish the oppressor in kind and that we should destroy towers in America in order that they taste some of what we tasted and so that they be deterred from killing our women and children." By the end of 2004, the US government proclaimed that two-thirds of the most senior Al-Qaeda figures from 2001 had been captured and interrogated by the CIA: Abu Zubaydah, Ramzi bin al-Shibh and Abd al-Rahim al-Nashiri in 2002;
