U.S. President Joe Biden on Tuesday defiantly rejected criticism of his decision to stick to a deadline to pull out of Afghanistan this week, a move that left up to 200 Americans in the country along with thousands of U.S.-aligned Afghan citizens.

In a televised address, Biden offered a sweeping defense of his handling of the Afghanistan withdrawal, saying he inherited an unstable situation from his predecessor, Republican Donald Trump, and that the 20-year war "should have ended long ago."

"I was not going to extend this forever war, and I was not extending a forever exit," he said, his voice rising with emotion as he spoke.
