I completely disagree!!!!
Reasons why:
If Kabuto did edo gin and kin then Naruto wouldn't of caught on something was wrong therefore Naruto wouldn't be there and all the Zetsu's would be trolling and killing people in disguise...
Then on top of that, Nartuo (And I guess bee) wouldn't be holding back Tobi and 6 f'in Jins! That all have a sharingan and Rinnegan each.
Tobi isn't stupid, he was going to declare a war with or without Kabuto because he still would of put on a good show!.
So to sum up, Zetsu would be raping from the inside whilst Tobi will be dealing with the army's best ninja on the front line
Any objections?
Edit: Plus if Kabuto didn't take Yamato and course trouble on the Island there is no way Naruto would know about the war!
COME ON GUYS!
