the supermarkets' delivery computers gone (so they don't know what food to send where) Oh no, they'd have to use the phone and or maybe messenger pigeons, or just guess - roughly that much food. How did all of this work in the early 1900s and earlier - magic? We couldn't possibly fall back to that, could we! the oil refineries gone All of them? They all had centrifuges or what not, connected to the Internet, and all of them were destroyed by a stuxnet style of attack, all at the same time? the power stations down All of them too? Really? How likely is all of this to happen at the same time, in such a totality? NY lost power for 48 hours in the middle of summer not that long ago, almost all of the North East did - no riots. If all of what you describe happens, we might see a lot of food riots. But I don't think millions would die, people would feverishly work to bring the power plants and refineries back up. But ALL of what you describe happening at the same time is an extremely unlikely scenario, and I mean extremely unlikely. the communications net down so people can't co-ordinate to get everything up and running. Short wave radio too? Really? Absolutely no way to communicate, let me throw some ideas out - Morse code and mirrors?
