Gen. Mark Milley, the chairman of the US Joint Chiefs of Staff, said in an interview with ABC News that he has “lots of regrets” over the way the US ended its 20-year of conflict in Afghanistan and “in the broader sense, the war was lost.”

“It didn't end the way I wanted it. That didn't end the way any of us wanted it,” Milley said. “Look, at -- when the enemy is occupying your capital ... that's a strategic setback, strategic failure. That's what I testified to in public. And there's no way you can describe that as a strategic success.”

"There is no doubt that America failed in Afghanistan; they didn't come here to leave without obtaining anything after twenty years. They had great goals, but the resistance of the Afghan people and the efforts of the Afghan people caused their defeat,” said Islamic Emirate spokesperson Zabihullah Mujahid.

Some military analysts said the withdrawal of American forces from Afghanistan was irresponsible.

"When a powerful nation leaves a territory, there should be a strategy, they should follow the procedures, and they should consult the people. Not in the way that we saw at the beginning, where there was a power vacuum and no responsible administration after they left," said Mohammad Matin Mohammadkhail, a military analyst.

This comes as earlier the US House of Foreign Affairs Committee Chairman Michael McCaul criticized the withdrawal of the American troops from Afghanistan.

“A true leader when they make mistakes, they own it and they take responsibility and they show accountability ... what these family members want is transparency and accountability, and yet this administration keeps trying to sweep it under the rug, and they don’t want to talk about it,” McCaul told FOX News.
