Comments on this post are pretty good. I like the idea of AUS or France, but family ties would not allow the Matson house to do something that drastic.
And while this is true:
A six month stockpile of canned/freeze dried goods and two dozen boxes of ammo won’t get you through it. You need a real game plan.
Being prepared enough to thrive during and post the initial system shock will go a long way. Not being hungry or completely defenseless will help you think clearly. I propose that you have 12 months + worth of supplies. It is cheap, an excellent investment against all kinds of systemic vulnerabilities, and will give you the ability to render direct aid to those around you, further building your tribe in times of crisis.
The ability to defend the above seems only logical.
