COMBO-US-NKOREA-NUCLEAR-DIPLOMACY-TRUMP

(COMBO) This combination of pictures created on October 1, 2017 shows, US President Donald Trump at Morristown, New Jersey, Municipal Airport on September 15, 2017; and North Korean leader Kim Jong-Un waving following a military parade in Pyongyang on April 15, 2017. Trump said on October 1, 2017, negotiating with North Korea over its nuclear program would be a waste of time, after it emerged that Washington had channels of contact with Pyongyang. Only hours after US Secretary of State Rex Tillerson revealed that US officials were in touch with North Korean counterparts, Trump undercut his top diplomat by declaring on Twitter that any talks would be futile. / AFP PHOTO / MANDEL NGAN AND ED JONES (Photo credit should read MANDEL NGAN,ED JONES/AFP via Getty Images)
