..... Kim Jong’s rockets can only travel a few hundred miles at most .... so why are we panicking? Japan and S Korea are the ones that should actually be worried about this.
Iran has launch vehicles that work. Bowl head has the warheads (in theory).
FYI - the most plausible scenarios have the missiles launched offshore from ships. They could reach sufficient altitude to generate the three-phase line-of-sight most-damaging EMP effects. Otherwise intra-atmospheric EMPs would be localized and arguably 2-phase. Ground burst, or near-ground burst are far worse fallout risks than EMP risks.

Care to reconsider your contempt for its capabilities?
