The irony is that IF they succeed in destroying this country (as we recognize it), they will mostly be located in cities (i.e. dependent upon the countryside and a fully functioning food-growing, food-processing and transportation infrastructure to merely eat), and they will also be on the short end of the stick regarding firearms (I am sure that fully 80% are located outside of cities, and that probably 90% of the expertise as to how to care for, use and reload them resides in the minds of those outside of the cities).
So, IOW, they are screwing themselves and they don’t even realize it.
