I think this topic warrants its own thread because of the many, many updates. Here is the latest as of 9/14/17: https://www.nytimes.com/2017/09/14/world/asia/north-korea-missile.html North Korea Launches Another Missile, Escalating Crisis By RUSSELL GOLDMAN SEPT. 14, 2017 HONG KONG — North Korea fired a missile off its east coast on Friday, the South Korean military said. It was the 15th such test this year and the first since North Korea detonated its most powerful nuclear bomb to date. In Japan, an alert was issued on television and via cellphones, warning people to take shelter inside a building or underground. The Japanese government said the missile flew over Japan and landed in the sea some 1,200 miles east of Hokkaido. South Korean officials had said recently that intelligence reports indicated that the North Koreans planned to test an intercontinental ballistic missile. The North’s scientists have for decades worked to build both a nuclear device small enough to fit on the tip of a long-range missile and such a missile — an ICBM able to pierce the atmosphere, return to Earth and reach a target thousands of miles away. The North’s missile program had been known more for failures than successes until it made a rush of advances this year. Analysts say a powerful new engine lies behind a string of successful tests, and as a result, the North has increased the frequency and potency of its experiments. North Korea has launched more than 80 missiles since Mr. Kim came to power in 2011. It last tested a missile on Aug. 28, when it fired an intermediate-range missile over Japan. That missile, which flew 1,700 miles before crashing into the sea, led the Japanese government to issue emergency warnings to the public. A Moody Young Man With a Nuclear Arsenal Once dismissed as a figurehead, Kim Jong-un has used purges and crafty moves to exert firm control over North Korea and its expanding nuclear arsenal. A month earlier, on July 28, the North tested an intercontinental ballistic missile that reached an altitude of 2,300 miles and that experts said had the potential to hit the West Coast of the United States. The recent missile tests have been made more troubling — and provocative — by the North’s pursuit of nuclear weapons. This month, the country detonated its largest nuclear bomb to date, a device four to 16 times larger than anything it had previously tested, according to experts. The nuclear and missile tests have strained the region’s nerves, led to an additional round of international sanctions and challenged the Trump administration to project a cohesive policy on the conflict. Last month, Mr. Trump threatened that North Korea “will be met with fire and fury like the world has never seen” if the country continued its provocations. Soon after, the North said “an enveloping fire” would surround Guam, an American territory in the western Pacific where the United States operates an Air Force base. Guam, like South Korea and Japan, is a likely target of the North’s aggression, should the conflict on the Korean Peninsula escalate. In August, the United Nations imposed punishing sanctions on North Korea. After this month’s nuclear test, President Trump threatened China and South Korea with restrictions on trade with the United States in the hope that they might pressure their neighbor to cease its tests.
