Watch Live: Biden defends Afghanistan exit after war ends

Washington — President Biden is addressing the American people Tuesday afternoon following the end of the nation’s two-decade-long war in Afghanistan, which came to a close Monday with the departure of the final U.S. military aircraft from the main airport in Kabul.

The president began by touting the military evacuation of thousands of Americans and Afghans, one he called successful even as Americans and vulnerable Afghans who helped the U.S. remain in the country. The president also lamented the deaths of 13 Americans who died in an attack at the Kabul airport, saying the U.S. will never forget them. 

“No nation has ever done anything like it in all of history,” the president said of U.S. evacuation efforts. “Only the United States had the capacity and the will and the ability to do it, and we did it today.”

The president emphasized that Americans in Afghanistan were told 19 times to leave, as he said 100 to 200 remain in the country. Most of them are dual citizens, he said. The Pentagon admitted Monday that Americans who wanted to leave were not able to make it to the airport. 

“The bottom line, 90% of Americans in Afghanistan who wanted to leave were able to leave,” the president said. “And for those remaining Americans, there is no deadline.” 

CBS News has learned there are approximately 300 Americans still in Afghanistan, and the State Department has contacted roughly half of them.

The U.S. completed its historic airlift of tens of thousands of evacuees hours before Mr. Biden’s August 31 deadline for the military presence in Afghanistan to end. More than 122,000 people flown out of the country since late July by U.S. military and coalition aircraft, including at least 5,526 U.S. citizens. 

The final American plane, carrying diplomats and remaining troops, left Kabul at 3:29 p.m. ET, General Frank McKenzie, head of U.S. Central Command, said Monday, completing the U.S. withdrawal from Afghanistan.

U.S. diplomatic operations have been shifted from Kabul to Doha, Qatar.

Mr. Biden had pledged to end America’s longest war and announced in April that all U.S. military forces would leave Afghanistan by September 11, the 20th anniversary of the terror attacks that launched the military effort there. The president then announced in July the withdrawal would conclude August 31, ahead of his initial deadline.

But with the Taliban’s swift takeover of the country, culminating in Afghan President Ashraf Ghani fleeing the country, more than 5,000 U.S. troops were sent to Kabul to assist with evacuations of U.S. citizens and Afghans who aided American forces during the 20-year war.

The president faced pressure to extend his August 31 deadline to complete the U.S. exit from Afghanistan, but he said in a statement Monday that top military officials unanimously recommended the airlift mission end as planned.

Mr. Biden warned last week that U.S. forces on the ground in Kabul faced growing threats with each day they remained, and the final days of the war saw the deadliest day for U.S. troops in more than a decade.

A suicide bombing on Thursday by a member of the group ISIS-K, an affiliate of the terrorist group ISIS, killed at least 169 Afghans and 13 U.S. service members. In retaliation for the attack, the U.S. launched two airstrikes against ISIS-K targets.
