France on Mondaygave its highest award, the Legion of Honor, to three Americans and a Briton who subdued a heavily armed attacker on a high-speed train. “You have shown that in the face of terror, you can resist,” French President Francois Hollande said. Childhood friends Airman 1st Class Spencer Stone, Specialist Alek Skarlatos, and California college student Anthony Sadler, and British businessman Chris Norman disarmed, pummeled, and tied up the suspected Islamist militant, Ayoub el-Khazaani, who said he wanted to rob passengers, not massacre them.
