UN is not stronk. UN will never be stronk. Plus, they're forbidden to have any sort of military whatsoever - peacekeeping is technically different because it doesn't do any sort of aggressiveness. They wouldn't fund any sort of war products anyways since their mission is peace. Case closed. UN wouldn't even fund anything if it wanted to.

And about the US: they wouldn't fund something that game changing unless it was locked to the DoD. We have export bans on advanced stuff, which is why you don't see Canada flying around F-22s or anything like that. So for the government to fund a company that doesn't seem to have any loyalty to the US government (hell, isn't it not even based there?) and using its products not for the US government but for itself? That's impossible, simply because the protocols that the DoD has in place will guarantee that the most advanced technology is used by the US Military proper, and not some random corporation. Again, Lockheed Martin doesn't have any private F-22s that it can use or sell to anyone else. That stuff was funded by the government and in exchange all of it went to the Air Force exclusively. So even if the US can fund it, it won't.
