Naruto Shippuden Alternate events

*Spoiler* up to potentially episode 140 So what if Itachi chose to not prevent the coup d'etat of the Uchiha against the hidden leaf, would they actually have been defeated, I can't see the Uchiha losing this fight just because they are so powerful as fighters, not only that but the hidden leaf wouldn't have information on when the coup would happen because Itachi wouldn't be on their side telling them. Just wondering what other people think would happen past this point.
