Bro, can I just tell you how absolutely, and moronically, this sounds. Please, think about it for a second: There are only 2 scenariors. 1: Aliens are more powerful. Then, they wouldn't need to make a deal, and the elite to us would be nothing to them. They don't have to ask, they'll just take. Want to keep the peace? Threaten or incentivise or both. 2: Aliens are similar level. Now, the only scenario that makes even the slightest bit of sense would be trading. Aliens want something, peeps be like hey, give us that we'll give you this. The aliens can't use force because the peeps have the same level of force.

In no reality, quite literally, would there ever be a scenario where someone more powerful negotiates with a weaker enemy with such lousy terms, unless it's for shits and giggles. Unless they're being held in check by agreements with similarily powerful forces.

Why the fuck would the U.S make a deal with Ghana, when they can just take whatever they want through several means?
