Nonetheless the “cool” EMP device is silly compared to a nuke.
Physical damage vs lives and health.
“Physical damage vs lives and health.”
By “physical damage”, I assume you mean infrastructure - electricity, gas pumps, communications, vehicles, transportation to distribute food and goods, sanitation, hospital operations, etc. With EMP, lives ARE over, and health issues don’t matter any more. It’s just a more torturous way to die than with a nuke.
You should be aware that about 90% of the population would die in the first year following EMPLOYEES attack that takes the grid out. Additionally there would most likely be invasions and other attacks as well. We would instantly be thrown back to mid 1800’s technology.
