Lelouch V Britannia
From what I read Sasuke seems to be taking the Lelouch model of thinking. create a villain that the world will be too busy hating to hate each other, and be so powerful that no one can do anything about it. So the world will be at peace because no one can touch him, and they'll all hate him too much to hate each other.
Wrong headed thinking but Sasukes been about wrong headed thinking since his introduction as a character.
As I pointed out in my post Lalouch became the focus point of Hatred and then once he achieved this goal he sacrificed himself thus making his death the thing that united the two sides, Obito had unintentionally already managed the same feat, he united the five nations by making him the focus point of all the hatred, and then when Naruto defeated him, his defeat became a positive influence that united the nations.
This is why Sasuke's logic makes no sense, Naruto has already managed to unite the five nations, what Sasuke is doing is taking that positive unity and turning it into a forced one that will ultimately lead to hatred.
The sage is a even bigger idiot than he appeared last week, last week we didn't know Sasuke actually told him he wanted to kill Naruto. He pretty much set it up to Screw Naruto over, he gave Sasuke the power to kill Naruto, just because of a few hundred year old regret. Naruto can't even go all out no matter what, he needs the powers Sasuke has been given to free everyone from the Jutsu, but Sasuke doesn't need Naruto's powers. The Sage is a massive idiot.
