Trump's North Korea tweet 'not as bad as it might have been'

My nuclear button is bigger - and better - than your nuclear button. That's the message from President Donald Trump to North Korea's Kim Jong-un. Trump was tweeting in response to Kim's declaration earlier this week that he has a button for nuclear weapons on his table and the entire U.S. mainland is now within strike range. Historian and former diplomat in Korea James Hoare believes Mr Trump's tweet was "calmer" and "not as bad" as it may have been.
