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?
Sorry, I should have added that I would take along some basic tools to build and hunt with. I would also look for a place with an abundance of freshwater rivers and lakes and get the hell out of dodge (high density population centers).
It wouldn't be a solo effort, but my family is quite small. The goal would be to get as far away from people as possible and live in a completely self-sustaining way. Money of any sort would be completely unnecessary and I imagine Bitcoins would still be inedible at that point. The weapons would be for protection against any chance encounters with 'the bad guys'.
