As the OP, and thinking about - we buy oil leases from Sauron. Trump, Biden - whomever is president (assuming a US portal) go over for a fist bump and praise his genius.
If it's the Russians or Chinese - they will get along just fine. Will all be corrupted and our world taken over - perhaps - how could we tell except things might run more efficiently, given Sharps view of Sauron's executive abilities.
BTW, if Sauron won - what did Tolkien say he had planned. Another move across the oceans? The movie had the Shire just becoming a big industrial plant - making what and for whom?
Sauron sees export potential for cheap products and buying a good deal of tech?
