Every time North Korea does something provocative — which is often — Washington insists that Pyongyang must give up its nuclear weapons programme.
Days after North Korea launched its most high-tech intercontinental ballistic missile yet, US national security adviser H.R. McMaster said that US President Donald Trump "is committed to the total denuclearisation of the Korean Peninsula". Not that this line is confined to the Trump Administration. The Obama and Bush administrations before it also repeatedly insisted that North Korea must denuclearise.
That might have been a realistic aim before Pyongyang could build a hydrogen bomb and missiles that can reach the United States. It's just a matter of time before the North Koreans can put the two together — if they can't already.
The Trump Administration won't admit it, but North Korea is now a nuclear weapons power, analysts say. Why would Kim Jong Un's cash-strapped regime spend so much time and money on building these weapons only to give them up? And even if they were prepared to bargain them away eventually, why would they do so now, when Trump and his top aides are threatening military action?
"We've seen no indication in recent years that they are interested in denuclearisation," said Mira Rapp-Hooper, a North Korea expert at Yale Law School. "So it's difficult to rationalise how we are still so fixated on it."
