The top US military officer said on Monday that the United States would have to start making changes to its military posture on the Korean peninsula over time if talks with North Korea advance."The more successful we are in the diplomatic track, the more uncomfortable we will be in the military space," Marine General Joseph Dunford, chairman of the Joint Chiefs of Staff, told a forum at Duke University."Because over time, this negotiation will take a form where we're going to have to start making some changes to the military posture on the peninsula. And we're prepared to do that in support of Secretary Pompeo," Dunford said. He did not elaborate on what changes might be expected.
