Just recently, Secretary of State Rex Tillerson declared that the U.S. war of words with North Korea had grown 'overheated'. On Twitter, Trump batted down Tillerson's attempts to de-escalate the crisis. After Tillerson finished speaking with Chinese officials about the crisis in North Korea, Trump claimed that his Secretary of State was 'wasting his time'.
North Korea's foreign minister, Ri Yong Ho claims that Trump's tweets made the chance of nuclear war more likely. At the United Nations, Ri (Korean surnames are first in name order) claimed that U.S. had declared war on North Korea based on a recent tweet that the President had sent. No one knows what the U.S. will do on the Korean peninsula, even the President of the United States.
