SINGAPORE — President Donald Trump said he “developed a very special bond” with North Korean leader Kim Jong Un during their historic summit here Tuesday and proclaimed the start of a new era that could break a cycle of nuclear brinkmanship and stave off a military confrontation.“Yesterday’s conflict does not have to be tomorrow’s war,” Trump said at a news conference in Singapore following more than four hours of talks with Kim.Trump said Kim “reaffirmed” his commitment to denuclearization of the Korean Peninsula and also agreed to destroy a missile site in the country.“We’re ready to write a new chapter between our nations,” the president said.Trump sounded triumphant following his meeting with Kim, expressing confidence that the North Korean leader was serious about abandoning his nuclear program and transforming his country from an isolated rogue regime into a respected member of the world community.But Trump provided few specifics about what steps Kim would take to back up his promise to denuclearize his country and how the United States would verify that North Korea was keeping its pledge to get rid of its nuclear weapons, saying that would be worked out in future talks.“We will do it as fast as it can mechanically and physically be done,” he said of the process to rid North Korea of nuclear weapons.Trump announced that he will order an end to regular “war games” that the United States conducts with ally South Korea, a reference to annual joint military exercises that are an irritant to North Korea.Trump called the exercises “very provocative” and “inappropriate” in light of the optimistic opening he sees with North Korea.
