I don’t think the North Koreans have the capability to put something as heavy as one of their nukes into orbit, yet.
That was my point - a satellite is one thing, a nuke is quite another.
ICBMs do go into an earth orbit before heading back in on the target, so I assumed if you could do one you could do the other - but I can see from some of the comments that getting into orbit is only part of the equation.
