Tuned nuclear weapons detonated about 100 miles up. Three to four could due in most of the electronics in the country. That means computers, cars, trucks, airplanes, much of the electric grid, motors etc will be destroyed. Interesting that missile tests by our enemies, such as the DPRK, fail around that altitude.
That’s the attack you consider “logistically simpler” than a satchel nuke? Multiple tuned nuclear weapons detonated in low-Earth orbit over targets?
