Joe Biden calls Afghanistan War over amid hundreds of Americans stranded

President Biden, in a defiant address to the nation Tuesday, defended his decision to withdraw all U.S. troops from Afghanistan and shouldered full "responsibility" for the move -- while also blaming former President Trump and the Afghan security forces for the crisis leading to the Taliban takeover of the country. The president, from the White House Tuesday, addressed the nation just a day after the last U.S. troops left Afghanistan, marking an end to America?s longest war.
