First off, NoKo is a LONG way from fitting a Nuke warhead on any of their missiles..
Their 1st underground test fizzled, the second test worked... But again, that is a LONG way
from building a functional warhead that will fit in the nosecone of a modified skud...
It took the US, many years to get that far.. But then again, back in the 90s, we had
PRC spies at LOS ALAMOS.... They stole much of our supercomputer "W" programs..
Which are, the warhead design programs, Hmmmmmm?
They have been finding bits and pieces of these "W" programs in many places around
the world... Truly Dangerous!!!
