On Saturday, North Korea displayed its largest-ever intercontinental ballistic missile during a nighttime military parade in Pyongyang.

The size of the missile indicates that it might fly farther and carry a more powerful warhead than the Hwasong-15, its predecessor disclosed in 2017.

The New York Times said although the show-off of a new nuclear weapon is certainly a means to show North Korea’s military power, it was surely more a move to lift morale as Kim Jong Un struggled to keep his promises of economic growth.
