Actually, shorticus, I for some odd reason keep thinking your further away, not stretching into south Africa.

That said, the biggest thing the NAU would have issues with is aligning with any enemies of the NAU. Seperatists in the former upc being a big one.

If support was shifted to pro nau groups, I could see corporate entities being allowed to operate in some manner in the west. Be it supporting NAU troops in "restoring order" (taking new land) and aid operations, house building or what not.

NAU dont care about slavery. Its not allowed in the nation but they couldn't care less if others use them. 

If that all makes sense...
