I don't know where you live, but there certainly are none of them here.
I live in the USA. I would think that midwest, low population states like Wyoming and Montana would be one of few places "safe" from the effects of a third global war? Where do you live?
When and if total war happens, I'm looking for weapons, ammo, protective gear, and a boat...not bitcoins, or any currency, or even gold (unless I can make bullets out of it).
With these materials, how would you intend to feed and clothe yourself + the family you are protecting (if you don't have children, let's include your elderly parents, uncles, aunts, cousins, etc)? I would think it would be easier to find a quiet place in the world to farm/sharecrop, work, trade, etc. while the various nation-states fight it out.
Back to my original question: where to go in the event of WWIII if one would like to stay out of the crossfire?
