As military leaders grapple with how to carry out President Joe Biden’s order to withdraw all American troops from Afghanistan by September, the Pentagon insists the U.S. commitment to the region is not wavering. "Just because we are removing our troops and our and ending our military mission in Afghanistan doesn't mean that we're walking away from the region," Pentagon Spokesman John Kirby told reporters Monday. "Nothing could be further from the truth," he said. Last week, Gen. Frank McKenzie, the commander of U.S. Central Command, said negotiations with Afghanistan's neighbors for overflight rights and troop basing are “moving forward” but will take time. On Monday, Defense Secretary Lloyd Austin spoke with Pakistan's chief of Army staff, Gen. Qamar Javed Bajwa. The Pentagon didn't get specific about what the two military leaders discussed, other than to says they talked about "shared regional interests and objectives." Commanders have said they will monitor threats from “over the horizon,” to ensure that terrorists cannot again use Afghanistan as a base to launch attacks against the U.S. But they have acknowledged that the U.S. does not yet have any agreements for basing or overflights from any of the neighboring countries. "There's still going to be a robust United States presence in the Middle East, in the Central Command area of responsibility," Kirby told reporters. "There's absolutely going to be no diminution of our commitment to our allies and partners in the region," he said.
