North Korea blames the deployment of a U.S. aircraft carrier for latest tensionsSEOUL, South Korea — North Korea warned Saturday the U.S. redeployment of an aircraft carrier near the Korean Peninsula is causing a "considerably huge negative splash" in regional security, as it defended its recent missile tests as a "righteous reaction" to intimidating military drills between its rivals.The Reagan and its battle group returned to the area after North Korea fired a powerful missile over Japan earlier this week to protest the carrier group's previous training with South Korea.He also called the Reagan's return "a sort of military bluffing" to issue a warning over North Korea's "righteous reaction" to "the extremely provocative and threatening joint military drills of the U.S. and South Korea."The recent weapons tests include a nuclear-capable missile that flew over Japan for the first time in five years and demonstrated a range to strike the U.S. Pacific territory of Guam and beyond.But some experts say Kim would eventually aim to use his advanced nuclear program to wrest greater outside concessions, such as the recognition of North Korea as a legitimate nuclear state, which Kim thinks is essential in getting crippling U.N. sanctions on his country lifted."
