SEOUL South Korean President Moon Jae-in has ordered a probe after the Defence Ministry failed to inform him that four more launchers for the controversial U.S. THAAD anti-missile system had been brought into the country, his spokesman said on Tuesday.The Terminal High Altitude Area Defense (THAAD) system battery was initially deployed in March in the southeastern region of Seongju with just two of its maximum load of six launchers to counter a growing North Korean missile threat.During his successful campaign for the May 9 presidential election, Moon called for a parliamentary review of the system, whose deployment has also infuriated China, North Korea's lone major ally. Before taking office on May 10, Moon Jae-in vowed to review the THAAD system's deployment, which has infuriated both Pyongyang and Beijing, which considers the system's powerful radar a security threat. Calling it a "very shocking" incident, South Korea's new liberal president on Tuesday demanded an investigation into why his office wasn't told by defense officials about the arrival of several additional launchers for a contentious U.S. missile defense system meant to cope with North Korea's nuclear threats. BOMBER DRILL

 The United States, which has 28,500 troops stationed in South Korea, has a mutual defence treaty with Seoul dating back to the end of the 1950-53 Korean War, which ended in a truce that has left the peninsula in a technical state of war.South Korea's Defence Ministry said on Tuesday it had conducted a joint drill with a U.S. supersonic B-1B Lancer bomber on Monday. Japanese Prime Minister Shinzo Abe talked to Moon by phone on Tuesday and told him that dialogue for dialogue’s sake with North Korea would be meaningless, and that China’s role in exerting pressure on the North was important, Japan’s Foreign Ministry said in a statement.
South Korean President Moon Jae-in, who had campaigned on a parliamentary review of the country's missile defense system, orders an investigation of the anti-missile system after discovering the government was not informed when four more U.S. Terminal High Altitude Area Defense (THAAD) system launchers had been brought in and installed.
