He already has great army and power big enough to conquer men and elves of ME.
Is it personal power? He is allready immortal, has the power to torment earth itself.
Is it only that there is never enough power or is it something else? Fear that new Lord of the rings would be stronger than he is? What do You think?

In part it's because he'll never be secure as long as someone else might get it. Once he figured out that Gollum had it, and it's now in the hands of a (shudder) Hobbit, he knew he had a problem.

Besides, the One Ring ought to be on any Dark Lord's list of want to haves.
