When was the last time American presidents sounded much more refined, mature and sophisticated? The reality in 2018 seems to be further deteriorating.
On July 22, U.S. President Donald Trump explicitly warned Iran's president, tweeting all in capital letters, that Tehran "should never, ever threaten the United States again." He said Iran would "suffer consequences" that "few throughout history have ever suffered before," and that the U.S. will not "stand for your demented words of violence & death. Be cautious!"
Many in Tokyo were appalled because we never expected the U.S. president would sound so coarse and undiplomatic.
