"BTW, in the Russian configuration, that missile had much more range. The North Koreans adapted them to carry heavier payloads."

I'd bet that's because the NorK and Iranian warhead designs are not as lightweight as the Russian ones. It takes a lot of development to get from a nuke that works to one that is light enough to package on a missile. Look at the size of Little Boy and Fat Man versus modern warheads.

Interesting... the last time I spoke with my Iranian and Pakistani sources I was told that Iran has already completed a total of six "uranium bombs" ~ when I refered to them as nukes, the Pakistani smiled and corrected me and once again said they were "uranium bombs".

The problem I was told was that these "uranium bombs" were too heavy.
