Seoul (South Korea), March 4 (LaPresse) – The sister of North Korean leader Kim Jong-un has threatened a high-profile response to the arrival of a U.S. aircraft carrier in South Korea and other U.S. military activities. Kim Yo Jong described the activity in South Korea as "hysteria from the United States and its henchmen." The USS Carl Vinson arrived in South Korea on Sunday, the latest temporary deployment aimed at demonstrating the strength of the U.S.-South Korea military alliance. North Korea views the proximity of powerful U.S. military assets as a threat and often responds with missile tests.
