No one really knows what North Korea’s leader is thinking.

Heritage’s Bruce Klingner, senior research fellow in the Asian Studies Center, was interviewed on ABC’s World News about Kim Jong-un, North Korea’s mysterious dictator.

“Very little is known about someone whose finger is on a nuclear button,” said Klingner, former head of the CIA’s Korea Unit.

Despite its leader’s dangerous nature, Klingner says he does not think North Korea will launch a direct attack on the United States, saying, “They would know that that would be national suicide.”
