Obito's plan was decent

[USSJ Future Trunks]

he probably didnt need kabuto IMO.
the first day was actually just a setup for nighttime when zetsus started chaos in the camps by posing as alliance shinobi. the only thing that stopped it was sakura. she captured one alive, and interrogated it enouugh to find out their power and plan, then reported it to HQ who recalled naruto. now this was also playing into obitos hands but left a stronger alliance than if sakura had not been there to cut the assasinations short. if not for her the whole medical division would be in chaos.
second thing he didnt count on was naruto. gedo + chains + kamui was enough to handle bee but naruto proved just too strong for zetsu army/edo jins due to gaining control over kyuubi. with just SM he really wasnt that much of a threat and without madara there the kages would wait evne longer to get involved, possibly too late, thinking they were winning easily when the two jins were being captured. it was a pretty good plan to lure naruto out and demolish the medic division. but alas plot power.
obito was a one man army anyway and with salvos he could walk in, wreck a division, warp out. rinse and repeat.

If it wasn't for Edo-Madara Obito wouldn't stand a chance against N&B team and Kakashi-Gai...He was at the limit, if it wasn't for Madara , the kages would face Obito together with all the Shinobi Alliance =/. But that's an hipothetic case, its better like its now, we will reach to know all the story from Madara's mouth and possibly we'll see the Juubi going rogue against everyone (Rikudou could wistand the Juubi because of his strong chakra but Obito only has the Eyes of the Older Brother and Naruto the body..)However nice theory your's :P

We actually don't know his limit yet.

& I had a similar theory, why could Tobito not warp in, steal the Jinchuriki 1 by 1 and warp out to an Akatsuki hideout where all the members could collaboratively beat the hell out of said Jinchuriki, seal him up, and rinse and repeat. Alas the plot is broken...

I would agree that he had a solid plan, but we also have to think that without Kinkaku going Tailed Beast there is a chance Naruto doesnt sense anything from the special room and The Zetsu infultraters go nearly unapposed as no one can sense them! With a stubborn Raikage Naruto doesn't head out until massive casualties. Also the lack of Madara and the tailed beasts means Naruto doesn't fully bond with Kurama! It makes Obito's job much easier!

good thought!!!

I just think he haw to show something more impresive than Impure World Reincarnation.Otherwise, he would not risked.
