The U.S. military is flexing its muscles after North Korea's latest intercontinental ballistic missile test. The U.S. flew two B-1B bombers over the Korean peninsula Sunday. They were joined by Japanese and South Korean fighter jets. The U.S. also says it successfully tested its THAAD missile defense system in Alaska. The system is designed to intercept and shoot down ballistic missiles. North Korea tested a missile on Friday that could possibly reach portions of the U.S. mainland.
