If North Korea wants to put Satellite into Orbit, what should it do ?

[Ezana]

I am no fun of the N Korean Dictator, but I have one question about his recent satellite launch and the reaction from the US, S. Korea, Japan etc.

If the N Koreans want to launch Satellite and explore space, must they rent other countries' rockets ? Could not they develope their own rocket ? Do not other countries, apart from those who have already developed the technology, have the right to progress ??
