North Koreawill be fielding modern solid propellant missiles.
This is a natural development. Missiles and missile technology are their only real exports, and, absent a nuclear capability (which we don’t want them to have) it is their only credible deterrent.
Furthermore, these weapons are legal.
Of course, you have a former Bush administration official *cough* corrupt incompetent *cough* and a US Army general *cough* Bush Toady *cough* acting as if the sky is falling.
The North Korean has a very real fear of a sneak attack from the US. As long as Cheney is anywhere near the levers of power, this fear is justified.
Even if the fear were not justified, the best course of action is to attempt to reduce that fear, rather than stoking it with bellicose and jingoistic rhetoric.
