In April, when President Biden announced his intention to end the United States’ military mission in Afghanistan, he told Americans and the world, “We will not conduct a hasty rush to the exit. We’ll do it responsibly, deliberately and safely.” Four months later, the U.S.-backed government has fallen in a matter of days; Afghan citizens, embassy staffs and members of international development organizations have been left scrambling toward the airport. In an address last month, Biden said, “It’s up to Afghans to make the decision about the future of their country.” But by suddenly severing U.S. support for Afghanistan’s military, he took that decision for the Afghan people — and handed them over to the Taliban.
