3. The supposed disruption to satelites caused by a H= ANE seems to be based on what happened to Telstar and similar vintage space-craft. Surely satelite design has progressed since then, with better shielding and "radiation hardened" devices being used. If satelites are more robust then much of the reason for using RBR evaporates.

It could be that the concerns may be over the possibility of a North Korean missile sent in space to create an EMP and wiping out satellit= e communications
There is a difference between space equipment being "radiation-hardened" against the radiations normally found in space, and the neutrons. etc, that could be created by a nuclear device exploded in space.
