It's a much less informed reason. It's largely because it's not an area that I cover, but I would comment that North Korea is a significant potential threat. I wouldn't say it's a significant threat at the moment to North America, but of course if it continues along its current trajectory, there could well be at least a capability, though I would question the intention to be able to attack North America. I would question that intention because North Korea is very much focused upon its own regime survival rather than having some sort of strategic conflict in a more conventional way.
