Not good. Acting on its own self interests, which isn't always a dure thing.
Those self interests aligning with ours, however, is, an indicator that this is not just an extinction level threat, because there are lots of those where they don't ever, but a fucking bad one.
Unless they're airlifting it all out. In which case it still has to fly over terrain that's not to their advantage. And we also make the missiles here.
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.
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.
Maybe they could get corn and wheat.
Or maybe you could get marines to pick apples, if you didnt give a single shit about the morale of your troops, health of your trees, abysmal recruiting numbers, already too-small military...
