You have asked a pertinent question.
My response is that there is Nebraska and then there is Nebraska and then Kansas and maybe even Colorado. There is Omaha and Kansas city then there is Nebraska and Kansas.
The leftist concentrations are in the cities. The cutoffs would be in the large metro areas. It’s very possible that neither Omaha nor KC would be affected. It’s also possible that any outage there would be swiftly corrected and saboteurs captured.
I personally do not believe those that go on defense in cities will have the wherewith all to leave and travel to selected targets in the vast red zone. Nebraska should be safe and that might well include Omaha as well
I happen to know personally which subs to disable to cut the power to most of the west coast.
And they aint anywhere near the west coast.
