Trump explains why North Korea can have nuclear weapons but Iran can't

US President Donald Trump was asked why North Korea can have nuclear weapons but Iran cannot. Blaming previous governments for failing to stop North Korea's nuclear programme, Trump said, "I'm...the only person in...entire world that Kim Jong-un likes...As long as I'm around, he'll be fine." In 2017, a war of words between Trump and Kim escalated to nuclear war threats.
