U.S. Officials Believe Terror Groups Will Grow Faster Than Expected Amid Taliban Takeover

U.S. officials believe terror groups will grow faster than expected with the Taliban's takeover of Afghanistan after entering the capital city of Kabul on Sunday, the Associated Press reported.

The chairman of the Joint Chiefs of Staff, General Mark Milley, spoke with senators on a briefing call Sunday. He said U.S. officials are expected to change their analyses on how rapidly terror groups can rebuild in Afghanistan, a person with knowledge of the conversation, speaking on condition of anonymity, told the AP.

Top Pentagon officials warned in June that within two years of the U.S. troop pullout from Afghanistan, a militant group such as Al-Qaeda could resurge in Afghanistan and threaten U.S. security.

"The Taliban has lots of reasons to honor their agreement with the United States and keep Al-Qaeda at bay. And our mission now is to put ourselves in a position where we can monitor and verify that commitment," said Connecticut Senator Chris Murphy.

The warning from America's top general came as intelligence agencies charged with anticipating those threats face new questions after the U.S.-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.

Two decades after the U.S. invaded Afghanistan because the Taliban harbored Al-Qaeda leaders, experts say the Taliban and Al-Qaeda remain aligned, and other violent groups could also find safe haven under the new regime.

The Biden administration officials on the call with senators—including 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." The official was not authorized to discuss the matter publicly and spoke on condition of anonymity.

But President Joe Biden didn't suggest such an outcome at a July 8 news conference, when he said that "the likelihood there's going to be the Taliban overrunning everything and owning the whole country is highly unlikely."

The reduced U.S. troop presence in Afghanistan—down to 2,500 troops at the end of President Donald Trump's term—may have hindered intelligence efforts in Afghanistan. Retired Lieutenant General Robert Ashley, who led the Defense Intelligence Agency until October, said having fewer Americans embedded with Afghan forces meant there was less insight into how those forces would perform.

"It's very, very difficult to gauge the morale down at the unit level because you're just not there anymore," Ashley said. "And I wouldn't be surprised if Afghan leaders would tell us only what we want to hear anyway."

Monitoring terrorism threats in Afghanistan will be even more difficult with U.S. troops withdrawing and the Taliban in control. Intelligence agencies in Afghanistan work side by side with troops. Without the same military presence, spies are severely limited in what they can collect about the morale of Afghan troops or support for the Taliban.

"If they leave, which they did, that means we leave as well," said Marc Polymeropoulos, who held several roles related to Afghanistan during a 26-year career in the CIA. "And that certainly affects our intelligence gathering footprint."

Murphy, a Democratic member of the Senate Foreign Relations Committee, said that once evacuations are settled that "our focus is going to shift" toward intelligence and counterterrorism activities. The U.S. will have to ensure it has the ability to track whether Al-Qaeda is reconstituting there, he said in an interview.

U.S. national security officials also briefed House members and tensions ran high. Republican leader Kevin McCarthy became furious after the administration officials would not confirm that President Ashraf Ghani had left the country, according to a person who participated in the meeting.

"Why are we doing this now?" McCarthy asked.

Ghani flew out of the country as the Taliban insurgents closed in on Sunday and posted on Facebook that he had chosen to leave the country to avert bloodshed in the capital. He did not say where he had gone.

Representative Michael Waltz, a Florida Republican and Green Beret who served in Afghanistan, sharply criticized the briefing as "a regurgitation of the president's statement" from Saturday.

Waltz said Austin blamed the Afghan forces' lack of will to fight, while Blinken cited the deadline set by former President Donald Trump's administration for an American withdrawal.

"There was no discussion of a path forward except some vague reassurances that they'll protect the homeland," Waltz said.
