In August 2017, the "Washington Post" reported on a confidential assessment carried out by the U.S. Defense Intelligence Agency which suggested that North Korea had successfully developed nuclear warheads for missiles within reach of the US mainland. Reacting to the report President Trump stated that future threats would be "met with fire and fury and frankly power, the likes of which this world has never seen before." In response North Korea announced that it was examining an operational plan to strike areas around the U.S. territory of Guam in the Pacific, including the Andersen Air Force Base. Officials stated that Joseph Y. Yun, the US envoy for North Korea policy, and Pak Song-il, a senior North Korean diplomat at the country's UN mission, were making regular contact during this dispute, through a conduit of communication they called the "New York channel".
