That’s the way it would work; electrical towers and sub stations blown, bridges blown, freeway overpasses blown, main water transmission lines blown, pumping stations blown, main and secondary roads IED’d.
Cut them off; let them die of thirst, starvation, and in the winter, freeze to death in the cold and dark.
In 7 weeks they would be hunting, killing, and eating each other.
I have a farm in a rural area where I am friends with 600+ horse & buggy Amish and Mennonite neighbors who all have farms too. They are/were tax clients..
I’m not concerned.
