After initially adopting a verbally hostile posture toward North Korea and its leader, Kim Jong-un, Trump quickly pivoted to embrace the regime, saying he and Kim "fell in love". Trump engaged Kim by meeting him at two summits, in June 2018 and February 2019, an unprecedented move by an American president, as previous policy had been that a president's simply meeting with the North Korean leader would legitimize the regime on the world stage. During the June 2018 summit, the leaders signed a vague agreement to pursue denuclearization of the Korean peninsula, with Trump immediately declaring "There is no longer a Nuclear Threat from North Korea." Little progress was made toward that goal during the months before the February 2019 summit, which ended abruptly without an agreement, hours after the White House announced a signing ceremony was imminent. During the months between the summits, a growing body of evidence indicated North Korea was continuing its nuclear fuel, bomb and missile development, including by redeveloping an ICBM site it was previously appearing to dismantleeven while the second summit was underway. In the aftermath of the February 2019 failed summit, the Treasury department imposed additional sanctions on North Korea. The following day, Trump tweeted, "It was announced today by the U.S. Treasury that additional large scale Sanctions would be added to those already existing Sanctions on North Korea. I have today ordered the withdrawal of those additional Sanctions!" On December 31, 2019, the Korean Central News Agency announced that Kim had abandoned his moratoriums on nuclear and intercontinental ballistic missile tests, quoting Kim as saying, "the world will witness a new strategic weapon to be possessed by the DPRK in the near future." Two years after the Singapore summit, the North Korean nuclear arsenal had significantly expanded.
