For months now, with the U.S. distracted by war in Europe, North Korean dictator Kim Jong Un has largely been free to accelerate his weapons programs.

President Joe Biden — along with U.S. allies Japan and South Korea — needs to start making life harder for him.

Kim’s scientists have conducted 16 missile tests since the beginning of the year, possibly including a failed launch of a gargantuan Hwasong-17 intercontinental ballistic missile. A new nuclear test may be imminent.
