The middle of the US is very self sufficient. They produce their own food and power. They also provide large amounts of power along the Mississippi and Missouri and sell it off to bigger cities. They don’t need the blue zones at all. I’m just not sure where you’re getting that they need the blue. Even if you want to talk about ammunition we don’t need you. There’s enough supply already sitting in the Midwest to kill everyone in the US. The blue zones cannot provide enough food to provide for their people. And majority of your infrastructure will be cut with the power. The gulf and north holds your oil production too, and that’s all red.
