It&#x27;s remarkably hard to plan for one without any idea of the &quot;shape&quot; it would take.  Region vs. region?  Faction vs. faction, which would geographically mix it up a lot more?  What would which governments be responsible for, and not?<p>The normal preparations would go some ways, everyone should have bugout plans, storage of food, water, essential medicines, etc., and while of course not recommended by most governments, basic arms, e.g. a rifle and pistol.  Beyond that, it&#x27;s really hard to say at this point, especially since we seem to be so far from one (for how long did our only Civil War brew?).
