Central Intelligence Agency Director John Brennan said North Korean leader Kim Jong-un is "exceptionally stubborn and not a very good listener," according to Voice of America last Friday.
Brennan made the remark at the Council on Foreign Relations in Washington last Wednesday.
"North Korea remains my top concern in terms of nuclear proliferation, as the country leader Kim Jong-un fails to recognize that the rest of the world won't accept his pursuit of nuclear weapons," Brennan said.
He added that the U.S. wishes to help North Korea emerge from isolation and to support the country's people. But he warned that Kim must realize that his pursuit of nuclear weapons and missiles harms the longevity of his rule.
