Those things aren’t cheap, you know, and they’re both trying to chew their way through their bonds, so I need to get hopping. ---

To those positing that the human race would manage to stand a chance against interstellar-tech aliens deadset on annihilating us… How do you propose defending against, say, a few modestly sized chunks of asteroid snatched from the belt on their way to our doorstep and slung at us from orbit? Orbital weapons would simply obliterate our manufacturing and population centers if they didn’t want to destroy the ecosystem by creating their own impact event. ---

There’s no political leadership, so we couldn’t even negotiate with them. Nothing to do but defend, fight back, and maybe domesticate a few, if we’re lucky. That sounds quite a bit like the Watchmakers from “The Mote in God’s Eye”. A non-sentient species that instinctively builds complex tools would be very frightening to deal with. ---

Perhaps the alien invaders come to hire/coerce meat-shield mercenaries to fight their battles against their arch enemies? Sort of a “We don’t fight, we have _people_ for that sort of thing” mentality. Through their off-planet research department they’ve found us, a nasty race with some really violent tendencies and a propensity for greed, but with blessedly fragile and short-lived bodies. And so They arrive, make wonderful overtures of peace and prosperity on our planet if only we could spare a few men and women to do job for them. Our leaders jump at the chance to gain alien tech and lose some excess population and thereby gain an edge over our own earth-bound rivals (I’m thinking of some really vile Cold War/Spy vs. Spy thinking here). So They then take off for home with a ship’s hold full of ‘volunteers’, give them unheard-of weapons and training at a staging site located on a moon far enough away from their home world that our rebellious nature won’t threaten their own stability and then ship them off to duke it out with the bad aliens. The survivors are then kept in captivity until needed again or die a natural death. The aliens could very think that they are being completely humane and only using a species that was born and bred for warfare and perfectly suited for this end. It’s like us using horses and other beasts of burden- they’re ideally suited for the task, so why not use them for the task? Just my thoughts, refute at your leisure.🙂 [Previous page](https://boards.straightdope.com/t/why-on-earth-okay-why-in-the-universe-would-aliens-invade/473288.md?page=4)
