The kind of scary thing is that if it was not for naruto as far as I can tell Tobi would have been fairly close to beating the army without Kabutos help. Once those clones started to transform things went south... actually we had not even started to see what they could really do in terms of Sabotage... What does nerve me a little is somehow I think Tobi had other things in his bag of tricks that he has not had to use since kabuto helped out. Well one thing for sure he could probably curb stomp half an army with his massive golem. lol

But I think Kabuto needs to thank Naruto! Because if naruto did not kill and beat pain not only would pain still be alive but more then likely pain could have or would have been used to revive madara or what ever Tobi meant when he said that pain was exposed to use that one jutsu on him! And that naruto really tossed a wrench in his plans when he beat pain. So I don't think tobi would have needed to rely on Kabuto if pain was not dead.
