U.S. Central Command Chief Frank McKenzie indicated Monday that the Taliban would have to change course abruptly for the United States to hold to a peace deal signed last February that calls for a full withdrawal from Afghanistan by May 1.

“Frankly, I remain concerned about the actions that the Taliban has taken up until this point,” the Marine Corps four-star general said during virtual remarks at an event hosted by the Middle East Institute on Monday, his first public comments under the Biden administration.
