evidence: Feb. 19 — Biden reiterates his campaign promise to bring U.S. troops home from Afghanistan, saying during remarks at the Munich Security Conference, "My administration strongly supports the diplomatic process that’s underway and to bring an end to this war that is closing out 20 years. We remain committed to ensuring that Afghanistan never again provides a base for terrorist attacks against the United States and our partners and our interests." [...] In a speech explaining the decision, Biden says he became convinced after trip to Afghanistan in 2008 that "more and endless American military force could not create or sustain a durable Afghan government." Biden says the U.S. achieved its initial and primary objective, "to ensure Afghanistan would not be used as a base from which to attack our homeland again" and that "our reasons for remaining in Afghanistan are becoming increasingly unclear." [...] "We will not conduct a hasty rush to the exit," Biden says. "We’ll do it responsibly, deliberately, and safely." Biden assures Americans that the U.S. has "trained and equipped a standing force of over 300,000 Afghan personnel" and that "they’ll continue to fight valiantly, on behalf of the Afghans, at great cost."
