Trump threatens kim jong un with military action after cancelling meeting
I'm not aware of any information that suggests President Trump threatened Kim Jong Un with military action after cancelling a meeting. In fact, the opposite is true.
On May 24, 2018, President Trump cancelled a planned summit with North Korean leader Kim Jong Un, citing "tremendous anger and open hostility" in a series of statements from North Korea. However, just a few days later, on May 26, 2018, Trump announced that the summit was back on, and that he would meet with Kim in Singapore on June 12, 2018.
During the lead-up to the summit, there were some tensions and disagreements between the two sides, but there is no evidence to suggest that Trump threatened Kim with military action. In fact, Trump and Kim exchanged letters and messages, with Trump expressing his desire for a peaceful and successful summit.
It's worth noting that the cancellation and subsequent rescheduling of the summit was a significant development in the diplomatic efforts between the United States and North Korea, and it marked a major shift in the tone and approach of the two countries.
