That is a dead on take.

You dont have to kill everyone in nuclear strikes. Destroy every single powerplant, radio station and port in a single strike and watch them going back to dark ages in matter of minutes.

No electricity and no communications means mass chaos. every city becomes a unsustainable trap with no supplies.

It would be terrifying to be in a middle of that. A nation that would tear itself apart for self preservation while all supplies are somewhere far out, 'in a place where food comes from'.
