Well, while I agree with that in principle, I don't think it is the case here. Both Sauron and Morgoth failed; and Sauron was defeated even when confronting non-Ainu level enemies. In fact, Sauron became so "insignificant", that Manwe considered it fit to delegate dealing with him to Men, even if he initially started off with angelic powers.

Manwe knew of Sauron, of course. He had commanded Sauron to come before him for judgement, but had left room for repentance and ultimate rehabilitation. Sauron had refused and had fled into hiding. Sauron, however, was a problem that Men had to deal with finally: the first of the many concentrations of Evil into definite power-points that they would have to combat, as it was also the last of those in 'mythological' personalized (but non-human) form.

I don't think that we can equate peace with whatever system of oppression Sauron had in mind. And, ultimately, I believe we can reasonably expect Sauron to become nihilistic too:

But in after years he rose like a shadow of Morgoth and a ghost of his malice, and walked behind him on the same ruinous path down into the Void.
