President Trump spoke on the phone Saturday, Washington time, with U.K. Prime Minister Theresa May about North Korea, Iran and other issues.<br />According to the White House, President Trump "emphasized his goal of a denuclearized North Korea."<br />His reference to North Korea specifically denuclearizing has drawn some attention here in South Korea.<br />It's a different goal than the one laid out in the Panmunjom Declaration signed by the leaders of the two Koreas a little over a week ago.<br />That statement called for a "Korean Peninsula completely free of nuclear weapons."<br />That could be an important distinction as President Trump prepares for his summit with Kim Jong-un. <br />
