My response to the other thread:
No, Naruto ultimately succeeded. The prophecy only entails that Naruto would succeed in promoting world peace and implicitly carry on Jiraiya's own legacy in reaching the point where everyone will understand each other and work in harmony. This is something explicitly illustrated even when characters such as Shin and Momoshiki who are inimical to world peace are opposed by all of the Kages who worked in unity to reach a common goal.
To be honest, people are delusional if:
Obtaining world peace.
Establishing empathy through Ninshuu.
Defying destiny by temporarily terminating the fued between Ashura and Indra.
Enabling Bijuu to be thought of as humans and function in unity with human beings instead of being weapons of mass destruction.
Suddenly denotes Naruto as a failure. Not only was Naruto subsequently stated to be the Child of Prophecy along with Nagato after Nagato's death, but KCM Naruto disproving Raikage's false preconception of Naruto confirmed that Naruto was truly the Child of Prophecy. Even after war, war enthusiasts will always be running amuck as was the case with Madara where Madara sympathizers were roaming around Konoha even after Konoha proclaimed Madara as a traitor. The existence of war enthusiasts is denoted as a natural consequence of war and there's literally no way to prevent this.
I'm a Sasuke fan, but even I wouldn't deny how Naruto was the most successful in obtaining world peace.
