Does North Korea's New Hwasong-15 ICBM Have Soviet and Chinese 'DNA'?

Kim Jong-un's new missile might have some secrets to it.  Does North Korea's New Hwasong-15 ICBM Have Soviet and Chinese 'DNA'? With photos emerging of North Korea’s massive new road mobile Hwasong-15 (HS-15) intercontinental ballistic missile, it is becoming evident that Pyongyang possesses a formidable 13,000km range weapon that can reach the continental United States. While there is some dispute about the exact capabilities of the HS-15, it appears that the missile is so large—and indeed North Korean statements explicitly state the weapon is designed to carry a “super heavy” warhead—that it might irrelevant if Pyongyang possesses warhead miniaturization technology or not.
