A significant majority of Americans doubt that the war in Afghanistan was worthwhile, even as the United States is more divided over President Joe Biden’s handling of foreign policy and national security, according to a poll from The Associated Press-NORC Center for Public Affairs Research.

Roughly two-thirds said they did not think America’s longest war was worth fighting, the poll shows. Meanwhile, 47% approve of Biden’s management of international affairs, while 52% approve of Biden on national security.

The poll was conducted Aug. 12-16 as the two-decade war in Afghanistan ended with the Taliban returning to power and capturing the capital of Kabul. Biden has faced bipartisan condemnation in Washington for sparking a humanitarian crisis by being ill-prepared for the speed of the Taliban’s advance.
