“isn’t everything connected to long wires?”
Not that long. EMP survival types claim EVERYTHING is going to melt, from watches, to cell phones, to car computers, and even our toasters. At most a signal could be introduced that confuses a computer or electronic device and causes it to temporarily malfunction. Reboot, or turn it off and on again, and all is well. They won’t melt. There simply isn’t that much energy in an EMP to do that.
Even that massive CME in 1989 that caused the northeastern power outage was massively larger than any EMP can be and all it did was blow a few transformers that were fixed within hours. No one’s cell phone melted. No watches exploded. No cars became disabled. And certainly not 70%-90% died from it.
Hmmmmmmmm
sounds good.
