Hi Waspie,
Long time no conversing - good to see you around again

I think you've hit the nail on the head here. Whilst one side argues that it was an attempt to launch a peaceful satellite into orbit and the other claims that it was a ballistic missile test the truth is that it was probably both.
I think you are right and it will be hard to distinguish the two. Since both essentially use the same launch technologies (a rocket/missile) putting a satellite into orbit goes a long way of testing missile delivery systems and their technologies. What they cannot test is obviously terminal guidance systems and the like. But if you can put something into orbit you can most certainly also deliver something in a suborbital path towards a target.

This rocket, in its current form, is pretty useless ad a weapon. It takes 5 days to erect, prepare and launch, is labour intensive and requires large facilities on the ground. This renders it impractical as either a first strike or a retaliatory weapon. Worse still North Korean nuclear weapons are in their infancy, meaning they are likely to be large and heavy and beyond the payload capacity of the Unha-3 launch vehicle.
Agreed on both counts. A liquid fueled rocket is a pretty poor delivery system and they certainly do not have a nuclear device with a satisfactory yield that could be fitted on any delivery system.

Placing a satellite in orbit would be a propaganda coup for North Korea. They want to portray themselves (not least to their own citizens) as an advanced country. Joining the small elite of nations with space capabilities would help. It would also be a bit of one-upmanship on South Korea, which also has a space programme but which has also suffered failures in its attempt to place a satellite in orbit.
Precisely. It would be a huge propaganda coup for the new leadership of NK.

There is also a diplomatic reason to launch a satellite. The 1967 Outer Space Treaty states that,
If the West then tried to prevent future launches North Korea would be able to claim that those nations were aggressors, interfering in its legal rights to access space.
Yes, nobody can prevent the peaceful utilization of space, no matter what one might think of the motives behind it.

So having made the argument for this being an attempted satellite launch, and that the Unha-3 is a fairly useless missile does that mean I don't think we should be worried? Far from it. As has been pointed out, what you can learn from a civilian launch can be applied to a military launcher.
It certainly can. If they can get a satellite up using a liquid fueled rocket, they can certainly do the same with a solid fueled rocket and then suddenly the path towards an ICBM is not that that long. Then the question is one of targeting and making a warhead that is actually deliverable.

It is worth pointing out that the Russians still launch Soyuz spacecraft using a derivative of the R7 rocket used to launch Sputnik 1 in 1957. It was originally designed as an ICBM, but (appart from payload capability) suffered many of the problems I have highlighted for the Unha-3. It too needed large ground facilities and took too long to erect, fuel and launch. So great were its problems as an ICBM that very few (I believe as little as 4) were ever deployed. However the lessons learned enabled the Soviet Union to design and build some of the most advanced missiles on the planet. North Korea does not have the finances or facilities of the Soviets, but they will have learned much, even from a failure such as this.
They have certainly learned a lot, but the Soviets at the time also had some very brilliant scientists and a lot of resources to throw at the problem.

The North Koreans have left the rest of the world with a dilemma, they are banned from ballistic missile tests, but have a legal right to explore and use space. If they continue to launch rockets in the guise of space exploration what can be done?
It is a very good question. If I knew the answer I'd write a book and get rich
Cheers,
