By the way, re-read the entire conversation that was at the summit. There's no evidence or implications that KA was broken or ended.
So quit with all the speculation.
That's not how debating works. We know how Genjutsu works and how Jins break it. By the implications set in the manga a Jinchuriki would break it. There's no evidence, no implications, nonothig point it to be unbreakable and I'm incline to go with what the manga has said and Jins break KA or any other Genjutsu for that matter. Itachi's Tsukiyomi is the only one that gives Jins the run around.
