America’s top general said the United States could now face a rise in terrorist threats from a Taliban-run Afghanistan. That warning comes as intelligence agencies charged with anticipating those threats face new questions after the US.-backed Afghan military collapsed with shocking speed.

Less than a week after a military assessment predicted Kabul could be surrounded by insurgents in 30 days, the world on Sunday watched stunning scenes of Taliban fighters standing in the Afghan president’s office and crowds of Afghans and foreigners frantically trying to board planes to escape the country.

Gen. Mark Milley, the chairman of the Joint Chiefs of Staff, told senators on a briefing call Sunday that U.S. officials are expected to alter their earlier assessments about the pace of terrorist groups reconstituting in Afghanistan, a person familiar with the matter said.

In June, the Pentagon’s top leaders said an extremist group like al-Qaida may be able to regenerate in Afghanistan and pose a threat to the U.S. homeland within two years of the American military’s withdrawal from the country.
Two decades after the U.S. invaded Afghanistan because the Taliban harbored al-Qaida leaders, experts say the Taliban and al-Qaida remain aligned, and other violent groups could also find safe haven under the new regime.

Based on the evolving situation, officials now believe terror groups like al-Qaida may be able to grow much faster than expected, according to the person, who had direct knowledge of the briefing but was not authorized to discuss the details of the call publicly and spoke to the AP on condition of anonymity.

The Biden administration officials on the call with senators – among them were Milley, Secretary of State Antony Blinken and Defense Secretary Lloyd Austin — said U.S. intelligence agencies are working on forming a new timeline based on the evolving threats, the person familiar with the matter said.

Current and former intelligence officials on Sunday pushed back against criticism of what was widely seen as a failure by the agencies to anticipate how fast Kabul could fall.

One senior intelligence official said that “a rapid Taliban takeover was always a possibility,” adding: “As the Taliban advanced, they ultimately met with little resistance. We have always been clear-eyed that this was possible, and tactical conditions on the ground can often evolve quickly.”
