while the United States promised its old foe security guarantees. The start of negotiations aimed at banishing what Trump described as North Korea’s “very substantial” nuclear arsenal could have far-reaching ramifications for the region, and in one of the biggest surprises of the day, Trump said he would stop military exercises with old ally South Korea. But Trump and Kim gave few other specifics in a joint statement signed at the end of their summit in Singapore, and several analysts cast doubt on how effective the agreement would prove to be in the long run at getting North Korea to give up its cherished nuclear weapons. “President Trump committed to provide security guarantees to the DPRK and Chairman Kim Jong Un reaffirmed his firm and unwavering commitment to complete denuclearization of the Korean Peninsula,” the statement said, referring to North Korea by the initials of its official name, the Democratic People’s Republic of Korea. The two leaders had appeared cautious and serious when they arrived for the summit at the Capella hotel on Singapore’s Sentosa, a resort island with luxury hotels, a casino and a Universal Studios theme park. Body language expert said they both tried to project command as they met, but also displayed signs of nerves. After a handshake, they were soon smiling and holding each other by the arm, before Trump guided Kim to a library where they met with only their interpreters. Trump had said on Saturday he would know within a minute of meeting Kim whether he would reach a deal. Trump later told a news conference he expected the denuclearization process to start “very, very quickly” and it would be verified by “having a lot of people in North Korea”. U.S. Secretary of State Mike Pompeo and North Korean officials would hold follow-up negotiations “at the earliest possible date”, the statement said.
