SEOUL, SOUTH KOREA — Some people in Seoul on Tuesday said they are happy just to see U.S. President Donald Trump and North Korean leader Kim Jong Un talking to each other rather than trading threats of war.
“I am very happy because it is an epoch breakthrough after 70 years of division,” said Lee Jun-keun, a salesman working for a retail business.
Last year the two leaders traded insults, with Trump calling Kim “rocket man,” and the North Korean leader calling the U.S. president a “dotard,” and they both threatened military action as tension rose over the North’s accelerated weapons testing to develop an operational nuclear armed intercontinental ballistic missile capability.
But after North Korea successfully test-fired missiles it claimed could carry nuclear warheads capable of reaching the United States, Pyongyang pivoted to diplomacy by suspending further provocations and indicating a willingness to engage in denuclearization talks. Trump surprised allies and adversaries alike by immediately agreeing to meet with Kim, long before the specifics of a nuclear deal could be negotiated.
Tuesday’s first meeting between a sitting U.S. president and a North Korean leader produced a broad declaration to rid the Korean Peninsula of nuclear weapons and develop a peace treaty to end the long standing hostiles between the U.S. and North Korea.
Trump called the agreement “very comprehensive,” but it will be left to negotiators to later resolve differences between Washington’s call for complete and verifiable nuclear dismantlement before any sanctions relief is provided, and Pyongyang’s demand that concessions be linked to incremental progress.
Some in South Korea remain skeptical that the broad commitment reached at the U.S.-North Korean summit in Singapore will lead to North Korea giving up its nuclear weapons program.
“North Korea did not keep its promise in the past, even after signing the agreement. This is what I am disappointed and doubtful about,” said Shim Jae-yeon, a housewife who lives in Seoul.
Others however offered praise for President Trump for keeping the diplomatic momentum moving forward, despite the lack of details in the agreement.
