"The nuclear button is always on the desk of my office," he said. "They should accurately be aware that this is not a threat but a reality."这两位领导人之间的最近一次口水战始于金正恩的新年致辞,他表示愿意与韩国谈判,并且声称全美都在朝鲜导弹的范围内。“核按钮一直在我办公室的桌子上,”他说。“他们应当准确意识到,这不是威胁,而是现实。”Trump responded via Twitter, saying, "I too have a Nuclear Button, but it is a much bigger & more powerful one than his, and my Button works!"特朗普通过推特回应道:“我也有核按钮,而且比他的更大更猛,同时我的按钮是有效的!”Critics said Trump’s tweet was too flippant and raised new questions about whether he understands the gravity of a potential nuclear war. But Haley said Sunday that Trump’s wording was an appropriate response to Kim’s statement.批评人士们表示,特朗普的推文过于轻率,还引发了新的问题——他是否理解一场潜在的核战争的严重性。但是,海莉周日说道,特朗普的用词是对金正恩声明的合适回应。
