Unless they're airlifting it all out. In which case it still has to fly over terrain that's not to their advantage.
Why would they have to fly anything out of the valley? If the military is able to secure supply lines in war zones that have more than small arms resistance I don't think it's going to be a challenge to secure them in Cali.
we also make the missiles here.
Who's we? It's not like the entire country is going to support a rebellion, especially not anyone in the military industrial complex. Even if you have missiles, you don't have the weapons platforms or even know how to operate them.
The best option for them would be the port of oakland. Theres lots of shitty tech bros there, but you still see tributes to the best and best dressed mlm's to ever pick up a rifle, some of whom are, while far past fighting age, still kicking around a dense high tech city-and this would be for their food supply line, so it wouldn't exactly be possible to starve them out.
What are you talking about? Why would food have to go to Oakland? You don't ship food from California to the rest of the country on boats.... Nor are some old dudes with small arms going to be able to do anything to military convoy.
The farms are all staffed by people who hate them. Every single one, not just here but especially here. Even the small/mid sized farmers-and i have talked to them-hate this shit, or are literally beibg chased out of the fields, literally as i type this. The logistics lines are disproportionately worked by those same people.
Work gangs, prison labour, political prisoners, hungry people willing to capitulate to feed their families.....you know the same thing that has happened throughout history. Plus, there's plenty of conservative chuds in the valley.
