The Taliban never kept secret what their reaction would be if the Biden administration delays the withdrawal of American troops from Afghanistan, and now that it’s happened, U.S. forces may have to deal with a new, unbridled wave of violence and bloodshed in the months leading up to the new September pull-out deadline.

Hours after news broke on Tuesday that following a “rigorous policy review,” President Joe Biden is planning to have all U.S. troops out of Afghanistan by Sept. 11—a break away from the previously agreed May 1 deadline—Taliban military leaders sat down for a policy review of their own. The group then announced it would be boycotting peace talks unless “all foreign forces completely withdraw from our homeland.”

Speaking to The Daily Beast on Wednesday, Mullah Salih Khan, a Taliban group commander from Afghanistan’s Helmand Province, said that the insurgent group is “very much prepared to strike,” against U.S. and Afghan government forces, warning that the militants will turn Afghanistan “into a nightmare” for them.

Mullah Mujahid Rahman, a Taliban subcommander from the Ghazni province, added that the U.S. has “proven they can’t be trusted after retreating from the May 1 deadline,” and that the group is willing to “fight till the end” of the U.S. presence in Afghanistan.

“We have the pride of defeating about 100,000 invaders from [different] countries in Afghanistan. A few thousand won’t be a problem at all,” he said, referring to the 3,500 American troops still stationed in the country.
