im preety sure they have to follow the hokage now after danzo was done, since they really want to protect the village. Even tho they were loyal to danzo their love to the village is stronger. Well if not tho, im preety sure tsunade would make them choose for a yes or no, either to join her or nah, if nah then its cool but they would be under surveilance or something, as well as the new anbu from the old danzo.
