[LOTR] Had Sauron regained the One Ring and conquered Middle-Earth, would, at some point, the Valar have intervened like they did with Morgoth?

I have my own ideas on this but I'm curious to see what others think about it.

It's possible, but there were quite a few reasons why they didn't want to do this. They don't interfere unless shits already hit the fan, and they would've likely waited a LONG time before they personally stepped in. If Sauron would've recovered the Ring they would've likely waited for Aragorn trying to rally the remaining kingdoms with Gandalfs help. They would've probably let Aragorns army lose and the entirety of Middle Earth being under darkness before they had a say, which after they wiped away the dark would reset middle earth and all the progress any kingdom had made would be undone. It would've been a huge setback and strenuous work to rebuild what evil can do in MidE. The only reason they don't step in sooner is, like most gods or demi-gods in fiction, they let the current occupants get as far as they can as them intervening doesn't necessarily help anything. Become too helpful and the population becomes dependent on God or Gods. Wait until the end and everything is ruined. It's really not a win for them in either of these scenarios, more of a reset. So yes, they probably would've stepped in, but now you see why they were putting all their cards on Gandalf helping Man make their own decisions, having him help indirectly at first, then when he died send him back with a buff on as they saw they needed to even the odds and allowed him to help more directly. Remember in the books however while Gandalf did fight directly it was still Man (led by Aragorn) calling the shots.
