“If the worlds most famous bird-watcher hits the USA with and EMP Weapon, he will get his Kimchi fried.”
And, if he does that, our wiping him and his country will help us HOW, exactly? It won’t restore our grid, food deliveries, power to hospitals, power for refining or extracting petroleum, etc., nor will it stop roving gangs of semi-starving barbarians from attacking anyone that they believe may have food and/or water.
Think about the whole package, not just one tiny element.
