Alright; title is a little short and blunt; but i have certain opinions on a matter and i want to know your opinions as well:
Do you think Naruto is not decently grasping matters and concepts he wants to handle?
Rest is my opinion; read it or not.
As presented through the manga; Naruto wants to be a kage, save the world, spread love and peace etc. But as far as i see; there is no deep grasping of concepts by him; he wants things; but he does not seem to be aware of mechanics. He is like a child who does not know how to drive the car but wants to do it regardless.
He just says he "understands"; he does not. He did not know zlich about Hyuuga clan and its situation; but he just says "imma change it cuz i don't like it". Everybody wants to change stuff. Wanting world peace does not make someone peace maker. He wants peace and good relations; but he does not know a thing on the matter. His tnj is laughable; it is baffling how people change themselves after hearing words that can be summed with "you and i are both the same, peace and love, don't be lonely, believe it dattebayo". I know this is a written story but it does not make sense how few words of another individual who is been met about a fight while ago can change life-long ideals.
All in all; i think he just want to be drive of things that he does not know internal mechanics of. I am not expecting him to be a political genius at such age; but does he ever stops and thinks "what the **** am i want and how will it happen; what can be the process?". He just neva eva gives up and wants peace.
If these concepts are never going to be grasped; i can assume that manga indeed suggests "believing it and never giving up" is the thing to know about the internal dynamics.
