Austin spoke to a small group of reporters in Kuwait City at the conclusion of a four-day tour of Persian Gulf states. He said the United States is prepared to prevent an al-Qaeda comeback in Afghanistan that would threaten the United States. I think that’s the nature of the organization.”The Taliban had provided al-Qaeda with sanctuary while it ruled Afghanistan from 1996 to 2001. The US invaded and overthrew the Taliban after it refused to turn over al-Qaeda leaders following the Sept. 11, 2001 attack on the United States. In a February 2020 agreement with the Trump administration, Taliban leaders pledged not to support al-Qaeda or other extremist groups that would threaten the United States.
