Fools or pressure from the Chinese to keep building?

I have no doubt the Norks easily could be doing this. On the other hand, this is another government agency reporting this, so when a government agency reports something, I would like more proof, than just their word.

Good points, all. FYI, here are more details on that "government agency" you had asked about.

It is a professional group of about 100 analysts, scientists, researchers, technical ops, etc. Satellite and photo interp.

The chief of the shop was interviewed last year on their methodology and how they keep us all safe.

The organization in question is fairly familiar, I believe they have credence; it is known as the "United States Air Force."
