President Biden’s churchgoing appears to be paying off. The first big international terror attack planned in the newly strengthened terrorist haven of Afghanistan struck Russia, not the U.S. Let’s hope Mr. Biden’s luck holds. A similarly audacious attack on America that was orchestrated in Afghanistan and involved operatives who entered through America’s chaotic southern border would hit the Biden administration like a nuclear bomb.
For now, it is who must manage the attack’s political aftermath. So far he is doing all he can to blame Ukraine and the U.S. for ISIS-Khorasan’s raid Friday on a concert hall near Moscow. This is neither surprising nor particularly effective. But what Mr. Putin must now face is a problem for everyone.
