'Dotard' vs. 'Madman': Kim Jong-un and Trump Trade Insults as Nuclear Anxieties Grow

President Donald Trump and North Korean leader Kim Jong-un traded insults early on Friday, continuing a war of words that's gone on for months, causing widespread anxiety over the possibility of a nuclear attack as North Korea conducts missile tests and Trump administration officials attempt to do damage control regarding the president's threats of retaliation.

The two leaders' statements have grown increasingly antagonistic, with Trump giving Kim the nickname "Rocket Man" last week and Kim introducing the arcane term "dotard" into the discourse Friday morning.

Three days after Trump's speech at the United Nations General Assembly in which he threatened to "totally destroy North Korea" if the Kim regime continues to test its nuclear capability, as it's done five times since July, Kim issued a lengthy statement comparing the president's threats to the barks of "a frightened dog."

Kim added that Trump "surely is a rogue and a gangster fond of playing with fire, rather than a politician," and called him a "mentally deranged U.S. dotard," using a relatively obscure word that Merriam-Webster defines as "a state or period of senile decay marked by decline of mental poise and alertness."

Trump responded on Twitter with his own shot at Kim's mental state.

Kim Jong Un of North Korea, who is obviously a madman who doesn't mind starving or killing his people, will be tested like never before!

The U.S. announced its latest round of sanctions on North Korea Thursday, penalizing foreign companies from doing business with the country and likely adding to the impact of its food shortage.

Meanwhile, a number of diplomatic officials and prominent activists have called for peaceful negotiations between the U.S. and North Korea. Defense Secretary James Mattis has warned against military action on North Korea, and on Friday, nearly 300 female leaders from 45 countries called on the U.N. secretary-general to appoint a special envoy to de-escalate the brewing tension. In a poll conducted by NPR/Ipsos just before Trump's speech at the U.N., 51 percent of Americans said they didn't approve of how the president has been handling North Korea's nuclear threats.
