You have leaders and followers, even among the Uchihas. Take away the leaders who cause the riot and either they lay low again or they cause another riot. Point is that you can't predict something like that. Even we can't assume something like that because we don't know what the personalities of the other Uchiha members was.One little question: Is the uchiha clan famous for lieing low and forgetting about revenge?
If they wanted peace why wld every shinobi among them decide to fight in the first place and reject offers of peace? (read the fifth point i added later)
Also what if they didnt lie low and DID turn out like sasuke? Even One person from the clan wld cause the death of millions if he turned for revenge. Wld u risk that?
And remember also that not every Uchiha awakened the Sharingan, much less the later stages of it. So if there were more non Sharingan left than Sharingan possessers, I think they would go for the smart move and lay low. Maybe they would try to take over later again, maybe not.
But in fact everything was started in the first place by Konoha itself when they banished the Uchihas to the outskirts and put surveillance on them. The Uchihas reacted to that distrust in such a way because they are a prideful clan. Maybe if Konoha would have showed them a bit more trust, a lot of problems could have avoided.
