Secretary of State Rex Tillerson said Wednesday there is not “any imminent threat” from North Korea, sending a message of reassurance a day after President Donald Trump threatened to unleash “fire and fury like the world has never seen” on Pyongyang. “Americans should sleep well at night,” Tillerson said, according to the Associated Press. “What the president is doing is sending a strong message to North Korea in language that Kim Jong Un can understand, because he doesn’t seem to understand diplomatic language,” Tillerson said Wednesday.
