If Madara wasn't there, Obito would have blown them all up with Juubi's TBB.
no because if kabuto did use edo madara obito was going to revive madara at FULL STRENGTH the same thing would of happened
WTF ?
But how will Obito revive Juubi without Madara ?
Madara helped him a lot.
Well the war wasn't even Obito's focus...by amassing the Zetsu it would have been a method for him to simply force Naruto out.
With the White Zetsu transformation, Naruto would have been pressed into action and Bee would've probably tagged along. This would have given Obito his chance to capture them....AKA the whole point of the war.
So I guess I agree since Obito wasn't really trying to win the war in the first place XD!
