WE MIGHT NOT GET EVERYONE OUT, BIDEN ADMITS.

Joe Biden admitted Friday that the U.S. might not be able to get everyone it wants out of Afghanistan as he said he could not guarantee the outcome of the “most difficult and dangerous airlift in history.”

The president said there was “risk of loss” in the evacuation amid warnings that 100,000 Afghans could be left to face Taliban reprisals.

NATO officials begged the U.S. to extend the Aug. 31 deadline for getting people out of the Afghan capital, as women were trampled outside the airport and it emerged some flights were leaving partly empty.

“Make no mistake, this evacuation mission is dangerous,” Biden said. “I cannot promise what the final outcome will be or that it will be without risk of loss.” However, the president said he would mobilize “every resource necessary” to rescue all U.S. citizens. “Any American who wants to come home, we will get you home,” he said.

Boris Johnson appeared to point the finger at Washington Friday over the debacle on Kabul's streets, where women were trampled in the chaos outside the airport that left visa-holders unable to board flights.

“When the United States decides emphatically to withdraw in a way that they have, clearly we're going to have to manage the consequences,” the U.K. prime minister said.

But Biden insisted again that no NATO allies had disagreed with his decision to pull out and said he could not send more U.S. “sons and daughters” to fight there. “I have seen no questioning of our credibility from our allies around the world. I have spoken with our NATO allies. The opposite, we're acting with dispatch. It's time to end this war,” he said.

Asked if he could get all Americans out by Aug. 31, Biden said: “I think we can get it done by then, but we're going to make that judgment as we go.”

Biden did not say what would happen to Afghans who had risked their lives helping U.S. forces, as Taliban fighters went door-todoor searching for interpreters. A German charity Friday said it had to shut safe houses it had set up to protect interpreters as the properties had become “death-traps.”

Reports of Taliban reprisals are growing, with an Afghan judge claiming that fighters had set a woman on fire after they disapproved of her cooking as they cemented control of the north.

There is also the looming threat that the Taliban could end their co-operation with Western forces. Asked how the coming days were going to play out, one senior U.K. defence figure gave a bleak assessment: “Not good. Eventually the Taliban will want their airport back.”

About 13,000 people have been evacuated on U.S. military aircraft since Aug. 14 and 18,000 people since the end of July, Biden said.
