Re:”If the EMP is solar in origin, then multiple countries may well be affected (depending on severity and angle of impact), and we could be on our own for quite a while. You can also be more confident with a solar EMP that there won’t be a nuclear exchange in the near future, so you don’t have to worry about nuclear war preps.” Yes, solar EMP does not affect the Far Side of the Earth, which could be any half. Note the available graphics on the 1989 Quebec blackout for more on that, via nasa.gov. Doug GonczExperimental MachinistI camped at the Jackass Flats site
I class technologies in three tiers: EMP-Proof, EMP-Susceptible, and Post-EMP-Required, and I keep 0 backups of EMP-Proof items, 1 backup of EMP-Susceptible items, and 2 backups of Post-EMP-Required items currently, in EMP-Resistant packaging when necesary. The categories do overlap. Your Mileage May Vary. I will be using QR Codes for the inventory soon. A paper backup makes that possible because internet connectivity is EMP-Susceptible.The QR Codes must be printed with an index number. I do believe that the EMP potential of the high altitude targeted nuclear arsenal increases the likelihood of a first strike to an unknowd degree, and rely on the geniuses at Federation of Atomic Scientists (renamed, I think), and The Club of Rome to twiddle those probabilties, but I do what I can, and move on.

No, the probabilities do not add.At least I don’t think they do.I have Kemeney’s Finite Mathematics text here to check this.Doug
