Here is a good Tobin Harshaw interview with Jeffrey Lewis, here is one good bit, scary in more than one regard:
Nuclear-armed missiles are a 1950s-era technology.
Well, there is a difference between the range the missile demonstrated last week, which was about 4,000 miles, and what the simulations we do at the Middlebury Institute suggest the missile may be capable of. My colleages, along with David Wright at the Union of Concerned Scientists, looked very closely at the launch of a new intermediate-range missile in May, as well as this one, trying to measure the missile and model its performance. It seems to me the North Korea cut the engines a bit early here, possibly so they did not overfly Japan. But they have been very clear their targets are in the continental U.S. — the Pacific Fleet in San Diego, Washington, and lately New York City — not Alaska. And our initial modeling of this missile suggests that it should be able to deliver a nuclear-weapon sized payload to most, if not all, those places. We’re still modeling away though.
I don’t think the North Koreans are going to deliberately start a nuclear war, but I think they might use those weapons if they thought a war was coming and they needed to get a jump on the U.S. and South Korea. And, despite the poor track record of decapitation strikes, the idea really frightens the North Koreans. But instead of making them behave, I suspect it will lead them to do things that I really don’t like, such as releasing nuclear weapons to lower level missile units.
Food for thought, the interview is interesting throughout.
