The North Korean leader said Saturday the second flight test of an intercontinental ballistic missile on Friday demonstrated his country can hit the U.S. mainland.
His announcement came hours after analysts concluded that a wide swath of the US, including Los Angeles and Chicago, is now in range of the dictator's weapons.
Kim expressed 'great satisfaction' after the Hwasong-14 missile reached a height of 2,314 miles and traveled 620 miles before accurately landing in waters off Japan.
The test was aimed at confirming the maximum range and other technical aspects of the missile it says was capable of delivering a 'large-sized, heavy nuclear warhead.'
Pyongyang's continuing development of nuclear weapons is a growing cause of concern for leaders in the United States, South Korea and Japan.
In a show of force against the dictator and his military, the United States and South Korea held a joint missile exercise in response.
