It has been said that this attack on October 7 was Israel’s 9/11. Each was an almost inconceivable attack on a prosperous, high-tech nation—by enemies thought incapable of accomplishing such missions, who used hardly any technology at all—that changed history forever. Audacious. Inhuman. Unimaginable. But not, as it turned out, impossible.

On Saturday morning, a quiet nonworking day for Israelis on the holiday of Simchat Torah, 2,500 Hamas terrorists carrying assault rifles and rocket-propelled-grenade launchers swarmed across a supposedly impregnable high-tech border. They shot out the cameras and sensors and punched through in 29 locations using bulldozers, ladders, and wire cutters.
