Madara persona wasn't hard to fool people with due to him having a mask and a sharingan, not to mention kamui making him seem invincible to others.
Well, yes, but I don't see how that makes him a genius
If you try and manipulate a kid who's life is already screwed up as is it shouldn't be hard to pull him to the dark side...heck, Madara did it with Obito.
His knowledge of shinobi hystory and ninjutsu comes from whom again?
As I said in my 3rd sentence, Sasuke's life was already screwed up. Wasn't too hard to manipulate him.
I'll give you the Konoha invasion, but you can't give him much credit for the way he did it, since he took an infant hostage and kidnapped a woman who had just given birth. You made good points, but sadly they don't prove Obito as a genius.
