I edited your post to add numbers, so I could respond with some organization.
1. It doesn't matter if it was a tech deal. It's incoming aid. I've already been paid for the 50 tech I owe to the Pacifican, but I'm not sending the tech until NPO is out of its alliance wars, out of respect for all the alliances (like mine) at war with them. Prior to sending this aid, AUT should have checked with Sparta.
2. You probably used some sort of trickery to convince people to send you aid, so they would not realize that you were in fact an enemy of NPO. The AUT was very well aware that RV is in an alliance war with Sparta, and knew that this could be considered a slap in the face. Also, when I was in NPO, people who aided Vox and FAN were considered targets.
3. Its enough money to pay bills for a good long while, which will avoid bill lock, which will allow RV to buy more soldiers, tanks, and aircraft to continue to terrorize small Spartan nations.
4. The Spartans attacking him have aid because Sparta is a well-organized, honorable alliance with many friends. What AUT is doing is not honorable, it is reckless and he may very well get his $@! kicked for it.
Basically, AUT knew what he was doing and did it anyway. Financing terrorism is never a good thing.
