KEY POINTS
  • The U.S. president isn't prepared to negotiate with North Korea's Kim Jong Un, strategists argue.
  • Trump "doesn't know a great deal about Korea — we know that he doesn't read very much, he watches a lot of television and his national security staff is sort of in chaos right now," Robert Kelly, associate professor at Pusan National University, told CNBC.

A looming face-to-face summit between President Donald Trump and North Korean ruler Kim Jong Un should be canceled, according to a political scientist who said the U.S. leader isn't prepared for such high-stakes negotiations.

The meeting is simply too risky because Trump apparently has a limited knowledge of North Korea's complex politics, Robert Kelly, associate professor at Pusan National University, told CNBC.
