After weeks of historic acts of amelioration, North Korea suspended a meeting with South Korean officials planned for Wednesday, and threatened to cut off the meeting with President Trump.
Here's what set off the North Korean regime
According to the North Korean state news agency KCNA, officials were angered by joint military drills between the United States and South Korea.
The summit between North Korean dictator Kim Jong Un and President Trump was scheduled for June 12 in Singapore. They were to discuss the possibility of North Korea denuclearizing.
"We are aware of the South Korean media report. The United States will look at what North Korea has said independently, and continue to coordinate closely with our allies," said White House press secretary Sarah Huckabee Sanders about the report.
"We have not heard anything from that government or the government of South Korea to indicate that we would not continue conducting these exercises," said State Department spokeswoman Heather Nauert, "or that we would not continue planning for our meeting between President Trump and Kim Jong Un next month."
Former CIA Director John Brennan blamed Trump for the reversal of fortunes in a statement to NBC.
"This turn of events is unsurprising since Donald Trump seems enamored with a fire-aim-ready policymaking process that is fraught with pitfalls as well as potential disasters," he said.
"Not sure when, if ever, Mr. Trump will realize that he is not the smartest man or even the best negotiator in the world," he concluded, "indeed, far from it."
"Just ignore it and plow on"
Karl Rove told Neil Cavuto on Fox News that Trump should completely ignore the threat from North Korea, and "plow on."
"I'd ignore it," he said. "Kim Jong Un is probably probing, seeing if he can get a response, can he, by rattling his cage, get the United States and South Korea to foreswear their training program, their military exercises?"
"I think the administration would be smart to just ignore it and plow on," he explained. "Let the onus be on him. He knew these exercises were coming, they earlier said they didn't object to them in their current form, and he's acting out to see if he can get a response, don't give him one."
