President Joe Biden’s Afghanistan disaster has endangered the lives of thousands of U.S. citizens and Afghan allies. But his bungling of security at the southern border will make it much harder to help tens of thousands more Afghans.

At least eight Afghans have died at the Kabul airport this week, as tens of thousands of U.S. citizens and Afghans try to flee the victorious Taliban. Amid the chaos and violence, the Taliban have set up checkpoints looking for Americans and European allies, reportedly beating women and children who fail to comply.
