See this is where we need another Kakashi/Gai team up fight. And instead of nameless Sand/Sound ninja it'll be two bodies of Pein. I think Danzou is just trying to protect Konoha. If Naruto came, Pein would get him, and then...well the 8-tails would be all they need to destroy everything.
This chapter has made me like Tsunade a little less. I always knew she was a bad Hokage but seriously. Kakashi needs to be Hokage already. You would think the guy who killed Jiraiya would make her want revenge also. Though fighting for revenge would probably get her killed faster.
You don't have to be strong to become a Chunnin. Just ask Shikamaru.
I think Konoha just needs to move. I mean really become a real secret village. They won't be attacked so much. And stop letting the strongest ones leave to die or turn evil.
