“I’d read that Elon Musk was selling his rocket technology to NK”
My mother read the Moon was made out of green cheese.
P.S. ICBMs no not need satellite guidance. They have “star finder” telescopes that locate known stars in the boost, glide and descent stages that do simple, computer-driven celestial navigation that gets them within 100 meters of a target.
With a nuc, that is VERY close enough. In addition, satellites can be destroyed or jammed. The star Polaris cannot.
You haven’t been watching the stars lately, have you? :)
