South Korea braces for another possible North Korea missile test

North Korea has previously marked key dates with displays of military power, but now its tests appear to be driven by the need to improve missile capabilities.

The North is just coming off its sixth and the most powerful nuclear test to date on Sunday in what it claimed was a detonation of a thermonuclear weapon built for its ICBMs. The country tested its developmental Hwasong-14 ICBMs twice in July and analysts say the flight data from the launches indicate the missiles could cover a broad swath of the continental United States, including major cities such as Los Angeles and Chicago, when perfected.

North Korea fired the ICBMs at highly lofted angles in July to reduce ranges and avoid other countries. But South Korean officials say the next launches could be conducted at angles close to operational as the North would seek to test whether the warheads survive the harsh conditions of atmospheric re-entry and detonate properly.

In Washington, President Donald Trump reiterated Thursday that military action is “certainly” an option against North Korea, as his administration tentatively concurred with the pariah nation’s claim to have tested a hydrogen bomb. A senior administration official said the U.S. was still assessing last weekend’s underground explosion but so far noted nothing inconsistent with Pyongyang’s claim.

“Military action would certainly be an option,” Trump told a White House news conference. “I would prefer not going the route of the military, but it’s something certainly that could happen.”

Pressed on whether he could accept a scenario in which the isolated nation had nukes but was “contained and deterred,” Trump demurred. “I don’t put my negotiations on the table, unlike past administrations. I don’t talk about them. But I can tell you North Korea is behaving badly and it’s got to stop,” he said.

North Korea broke from its pattern of lofted launches last month when it fired a powerful new intermediate range missile, the Hwasong-12, over northern Japan. North Korean leader Kim Jong Un then called the launch a “meaningful prelude” to containing the U.S. Pacific island territory of Guam and called for his military to conduct more ballistic missile launches targeting the Pacific Ocean.

Meanwhile, Sweden urged its citizens Friday to refrain from unnecessary trips to North Korea.

The announcement by the Swedish Foreign Affairs Ministry came hours after Mexico’s government said it declared North Korean Ambassador Kim Hyong Gil as persona non grata and ordered him to leave the country within 72 hours in response to Sunday’s nuke test.

The United States has already banned Americans from traveling to North Korea following the death of Otto Warmbier, a 22-year-old college student from Ohio who was released from North Korea in June in a coma after being detained there for more than a year.

Sweden has had diplomatic relations with North Korea since 1973. The Swedish Embassy in Pyongyang also provides consular services for the United States, Australia and Canada.

Also Friday, French President Emmanuel Macron and Chinese President Xi Jinping discussed North Korea by phone. Macron called for more pressure on North Korea to bring the country back to the negotiating table, and China’s official Xinhua News Agency described Xi as being “adamant” about the denuclearization of the peninsula while also expressing hope that France would play “a constructive role in easing the situation and restarting dialogue.”

South Korean experts say that the launch was Pyongyang’s attempt to make missiles flying over Japan an accepted norm as it seeks to test new projectiles in conditions close to operational and win more military space in a region dominated by enemies.

Kim, a third-generation dictator in his 30s, has conducted four of North Korea’s six nuclear tests since taking power in 2011. His military has maintained a torrid pace in testing weapons, which also include solid-fuel missiles built to be fired from road mobile launchers or submarines.

In accelerating his pursuit of nuclear weapons targeting the United States and allies South Korea and Japan, Kim is seen as seeking a real nuclear deterrent to help ensure the survival of his government and also the stronger bargaining power that would come from it.

Washington, Seoul and Tokyo have been pushing for stronger sanctions to punish Pyongyang over its nuclear activities, such as denying the country oil supplies. China and Russia have been calling for talks, saying sanctions aren’t working against North Korea.
