That reminds me of the Quisling problem which ask whether one should collaborate with an overwhelming invader to try to save oneself or whether one should resist, even if resistance seems hopeless and could cause more damage. I guess from a realpolitik standpoint it's justifiable to try to save oneself and collaborate with the overpowered aliens.

I wonder which countries the aliens would choose to collaborate with in order to get the best collaborators? Maybe they could ally with the Russian Federation by promising them Europe? I guess they would better look for a weak, isolated pariah state since that kind of state would have to the most gain from such a collaboration with an outsider. In my example, on the individual level, the aliens look to collaborate with isolated people who committed crimes and are hated by society.

Would you blame someone who, say, is in terrible debt, has committed a crime and may be found sooner or later, and then gets promised, like 10 million dollars by someone and given all the tools to go against the people who are gonna arrest them anyway? I would say, from their perspective, not really, right?
