White House: Lots of 'Tools' to Respond to Potential North Korea Missile Test VOA News White House national security adviser Robert O'Brien said Sunday he did not want to speculate about North Korea and its threat of "Christmas gift," but added the U.S. would be "very disappointed" if Pyongyang tested a long-range or nuclear missile. During an interview with ABC's "This Week," O'Brien said the country would take appropriate action as a leading military and economic power if North Korea went ahead with such a test. O'Brien added Washington has many "tools in its tool kit" to respond. "We'll reserve judgment but the United States will take action as we do in these situations," he said. "If Kim Jong Un takes that approach we'll be extraordinarily disappointed and we'll demonstrate that disappointment." .
