I've heard some ppl say that the tentacle of the hachibi and the chakra of kinkaku from the nine tails will act as a substitute to bring back the 10 tails. If thats true then I don't see tsunade and A trying to stop them because I don't know of any single person able to stop the jubbi. So they're probably figure this out and let them fight because the only reason they put then into hiding was to stop the 10 tails from being reborn. But if madara knows how to do it without naruto and bee, tsunade and A will realize they need them to fight.
I belive naruto will convince tsuande and A to let him pass, but not with talk per say.
I think he will show them a new jutsu,
the wind rasen bujj bomb.
They see the jutsu then realise that power must be used to rid the world of the demon statute which clearly the alliance have no answer to. But I wonder how would the dustjutsu would fair against the demon.
