Heh... Obviously, the modern nations can determine whether they were able to actually put a satellite into space...
Are they so backward that they think that it can be faked? Yes, for their people only - and that is all that counts.
The rest of the world laughs at them - but what do they care...
I think your question raises an interesting and important point. I don't know if they're so backward or deluded with paranoia that they don't understand that a satellite (and a missile for that matter) can be easily tracked by western powers. This is what makes them so incredibly dangerous - are they that stupid, that crazy or that cavalier with the safety of their citizens?
No one knows for sure. People can speculate - and the libs love to speculate that this is all just a ruse to get more aid. But, how can you negotiate with these people when there are so many variables that you just can't account for?
DPNK is on their way to an arsenal of nuclear bombs. They are on their way to a nuclear package that can fit on a warhead. And, they just demonstrated that they're well on the way to a delivery vehicle that can put an IBCM right on Hollywood and Vine. It seems to me that it's their strategy that's working - not ours.
