supply lines
Look at a map. Talk to the people in all the places you'd have to go through. Maybe if they let this die down, and start it with something other than a police action. But if this goes hot? From fed cops? No. The sierra-nevadas may as well be in afghanistan.
They wont be the hardest place in the country. That'll be between chicago or appalachia-but they will be a no-go zone for fed troops.
who's we
True, it wont be universal. I'm even seeing people in OC upset about this though, and if the admin's lost them, they've lost every major foothold with californians. Maybe downtown palo alto, for about five minutes. Maybe san diego, if they skew the demographics with a few aircraft carriers-but theres not much food between there, mexico, and the mountains.
old dudes with small arms
You don't even know what a maoist 'people's war' even is, and that's likely the doctrine they'll start with. You certainly don't know who the panthers were, or the kinds of people they were. You don't know what or where you're talking about.
chuds
Chuds can't and wont do real work. Not in numbers, anyway.
prison labor
Then the food all burns. Prisoners are busy.
other flavors of slavery
Notoriously productive resilient and efficient with their military resources: Slave States!
Plus, that'll really help keep the populace complacent. You know where the us military recruits from? You know how overrepresented african americans are in it? They do plantations, they cut off at least half of their troops, with only terminally online white boys to replace them. It'll be the posters army, and not even the good posters.
You play too many fucking map view strategy games. Go outside, maybe read a book. Or at least play the more complicated map games.
