Greetings. We are the Monogatrons. While your species was still toying with fire, ours mastered the science of functioning committed relationships. As the latest planet to develop our app you will now witness the true power of superior intimacy. – Monogatron leader from Rick and Morty
Just who wouldn't want do defect and join the invading empire when the masked enemies you were just fighting turn out to be inhumanly beautiful women? It's easy to stay affiliated with earth when aliens are ugly as hell or if they are a dictatorship. But what if their whole culture was really attractive? What if on top of being easy on the eyes and ears they were really good at statecraft? What if you simply didn't want to stay on this crummy planet where selfish people make everything more complicated? Especially after being shown that aliens have is so much better than us.
Culturally, there is nothing quite as destructive as foreign beauty. Had some traditions to uphold? Too bad. Some pagan women joined the chat. But this specific question is less about culture and more about nationality. Abandoning your country to join your parner's. That sort of thing. Knowing human nature, I can imagine that some leaders won't like that.
The Aluran empire, as they are called, are technically invaders though they is no ill intent behind their visit. They are simply elated to have found newcomers to their prosperous empire which is based based around the virtues of participation and good-will. And it turns out that about 67% of lyrics in every earth song are somehow about love. Close seconds are money, partying and depression. So these very attractive aliens see us as unfortunate lovesick beings. They're here to remedy that. Through interspecies relations!
However, they aren't here to openly share their resources. Part of the reason why their empire is so prosperous is because they lack that patriotic ideology or 'ego'. We act as if we were divided while we are actually one people. To openly share technology with earth is dangerous. We have our own interest in mind. We hoard resources. We fight. All because we have that egotistical mindset. In short, they're not sharing with us until we bend the knee and admit that we're all the same. And the problem is that not everyone agrees, which lead to this question.
If faced with this particular 'problem' how would earth's governments resist?
Your expertise is welcome. I didn't do my military service back where i'm from so I am woefully unqualified to make a proper assessment. I'm also bad a history and social sciences. And being human in general...
