"The U.S. continues to kick up the racket of frantic nuclear war drills even though the situation on the Korean peninsula is on the verge of the outbreak of a worldwide thermonuclear war", the commentary read.
Visits by US warships and bombers along with regular joint exercises with the South infuriate North Korea, which considers them a sign of aggression and a rehearsal for an invasion.
An unusually aggressive approach to the North by Trump, which has included rhetoric hinting at US strikes and threatening the destruction of North Korea's leadership, has some South Koreans fearful that war is closer than at any time since the Korean War ended in 1953 in a shaky cease-fire, leaving the Korean Peninsula still technically in a state of war.

The Defense Ministry after an investigation said in May that North Korea was likely behind the hacking of the Defense Integrated Data Center in September previous year, but had refused to confirm media speculation that the decapitation strike plan was compromised. "It is also consistent with the view of many other members of the global community to lessen, reduce or completely diminish any diplomatic relationship with North Korea". Some military experts believe that power supply problems make it hard for North Korea to turn on its air defense radars for 24 hours a day and also that the systems might struggle to effectively track advanced warplanes such as B-1Bs, which have low radar-cross sections.
The two B-1B bombers were accompanied by two F-15K fighters from the South Korean military after leaving their base in Guam, the South's Joint Chiefs of Staff said in a news release on Wednesday. The aircraft then conducted similar simulated air to ground striking drills off the peninsula's west coast, according to South Korea's Defense Ministry.
Among the leaked documents was Operational Plans 5015 for use in case of war with the North and including procedures for "decapitation" attacks on leader Kim Jong-Un, the paper quoted Rhee as saying.

According to one South Korean lawmaker, the country's hackers stole military plans developed by the USA and South Korea past year.
China, North Korea's main ally and trading partner, has consistently argued sanctions alone will not work, urging Washington and Pyongyang to lower their rhetoric and return to the negotiating table.
Professor Park, who first claimed that Carter is considering travelling to Pyongyang, has visited North Korea on at least 50 occasions and Shigemura suggested that the idea may have actually originated in Pyongyang.
