Survivalism makes a kind of sense in the US because there's enough space to live relatively self-sufficiently far enough away from marauding traumatised survivors. And they still have remnants of that pioneer spirit - which was quite a thing, in its way. The genocide of the Indians wasn't pretty, but it takes a certain kind of person to survive a trek across a continent in a covered wagon.

Survivalism makes no sense at all in Europe because population densities make survival unlikely, even with a gun and a small holding. The best solutions - but currently the least likely ones - have to be political.
