north korea in not capable of complex engineering and manufacturing. developing a nuclear weapon does not illustrate anything in that regard, what it does illustrate is that any nation with enough paranoia (or valid external threats even) and craziness can develop a nuclear weapon. its isolation was actually an obstacle in developing the said weapon and they had to collaborate<?> with china, russia, pakistan to develop them.
