U.S. flies nuclear-capable bombers and stealth jets as show of force against North Korea

The United States flew nuclear-capable bombers and advanced stealth jets in a show of force against North Korea on Tuesday, as the powerful sister of North Korean leader Kim Jong Un derided doubts about her country's military and threatened a full-range intercontinental ballistic missile test.  

The deployment of the U.S. B-52 bombers and the F-22 stealth fighter jets for joint drills with South Korean warplanes was part of an agreement to protect South Korea with all available means, including nuclear, South Korea's Defense Ministry said.
