Considering ACt's first post in the thread and AOTK's, they both hit the nail in the head, that Naruto's speech would actually be good if it wasn't for the context it unfortunately is in.
But I have to point out my biggest issue that wasn't mentioned (at least directly) until now: Naruto's analogy with shortcuts and long paths would only make sense if Naruto at the first clue about his long path to begin with. Knowing where the finish line is doesn't by itself solve the problem of figuring out the correct path, much like Naruto himself ironically pointed out. So the analogy really sticks out as improper pretty much because Part II denied the very thing it instigated Naruto to do, solve the conundrum of shinobi and peace.
