By the US side, EMP need not be caused by nukes:
EMP can be induced locally —even for individual buildings— by such weapons as CHAMP.
It uses no nuclear material.
This is what I believed to be the case.
That said, by using it in a way to take out as much infrastructure as possible, the US and Allies could concentrate on the 20,000 pieces of artillery.
It is my belief that we could black out communication within the North Korean military, and gain time to take out the 20,000 pieces of artillery, which could do great damage on South Korea.

I learned something new.
