North Korea’s ballistic missile program has shown drastic improvement in recent months. It conducted two tests in July of a new intercontinental ballistic missile, the Hwasong-14, that demonstrated a potential range of 6,500 miles, meaning it could hit the West Coast, the Rockies and much of the Midwest. But its statements about Guam have specified that it intends to use a different missile, the Hwasong-12, which is classified as intermediate-range and is fired from mobile launchers.
