Lots of veterans survived going to wars who live in the suburbs and cities, no? It's not just country folk that survive tough shit.
Sure. But cities don't survive when SHTF. Veterans or not.
The purpose of cities is to combine together to jack up production and create wealth. Invariably at the expense of rugged individualism and self reliance.
That's a bare fact.
When SHTF and the support network of a city fails, the people don't know how to take care of themselves. And inevitably, the end is eating your own.
Rural folks know how to make do, because they make do every day, all their life long. They will make it through when SHTF.
