Here is an interesting read from the Associated Press about what experts are saying about North Korea’s new ICBM:

North Korea released dozens of photos Thursday of the Hwasong-15, a new intercontinental ballistic missile it claims can reach any target in the continental United States. The photo dump, published in the paper and online editions of the ruling party’s official daily, is a goldmine for rocket experts trying to parse reality from bluster.

Their general conclusion is that it’s bigger, more advanced and comes with a domestically made mobile launcher that will make it harder than ever to pre-emptively destroy. But there’s a potentially major catch: it might not have the power to go much farther than the West Coast if it is loaded down with a real nuclear warhead, not a dummy like the one it carried in its test launch on Wednesday.  [Associated Press]

You can read more at the link, but experts are skeptical that the North Koreans have miniaturized their nuclear warhead to a low enough weight to where this ICBM can deliver it to the US West Coast.
