It really depends on the scale of a conflict. What I might be likely to survive would be something like a terrorist attack or some minor nation (like North Korea) going crazy. I don't think there is any public setup in my country that would allow large parts of the population to survive a global collapse in international trade combined with a nuclear winter that could last years. To survive something like that would require a full prepper setup. Like a cottage deep in the wilderness, with food storage for a couple of years, water for at least several weeks, lots of ammo for the rifle and all sorts of tools, seeds, etc required to start farming when the weather normalizes. That would be out of scope for me, as it would take up a large part of my life. Selecting a location to survive a minor attack is as easy as consider the view or access to infrastructure when buying a house, though.
