Actually, more than one reader has raised this question with me, so I'll briefly explain it.
It's mentioned in the plot, but I haven't elaborated on Itachi's inner thoughts.
It's simple: Itachi's rebirth occurred no more than three months after the Nine-Tails incident.
Specifically, the day after Sasuke was born was July 24th, giving him a total of seventy-eight days to prepare.
Itachi couldn't change the future on his own.
He could only rely on others.
This, in turn, ties into the reasons for the Uchiha clan's extermination.
The Nine-Tails incident, the death of the Fourth Hokage, and the Sharingan's ability to manipulate the tailed beasts were certainly major factors, but ultimately, the village leadership had harbored a fear of the Uchiha clan since Konoha's founding (not to mention the First Hokage, even during the First Hokage's time, he was probably the only one who treated the Uchiha clan fairly).
As a clan that once rivaled the current village leadership for power, the Uchiha clan itself was largely a proud group of individuals.
This, combined with the power of the Sharingan, contributed to the leadership's fear of the Uchiha clan.
When it comes to Uchiha affairs, the village's leadership has always maintained a calm and peaceful attitude.
When an Uchiha messes up, they seize the opportunity to suppress him.
Don't take this as groundless. The reason the Uchiha were placed in charge of the village security force was to create an environment where they could offend.
Itachi, fully aware of the Uchiha's predicament, had two options for changing their fate.
One option is to help the clan grow stronger, reaching a point where both civilian opinion and power are untouchable by the higher-ups (at this point, the Uchiha clan would hold real power in the village).
However, this path is virtually impossible to achieve, as the village higher-ups will absolutely not allow the Uchiha clan to grow.
Even with Itachi's assistance after his rebirth, it would be nearly impossible for the Uchiha clan to achieve this level of power under their watchful eyes.
Furthermore, this approach is extremely risky.
Exposing the clan too early could spark another war (even if the Uchiha clan harbors no rebellious intentions and simply seeks fair treatment, the higher-ups will only see them as a threat).
If the time is right and the Uchiha clan takes power, Itachi will then help the Uchiha clan suppress the higher-ups' coup.
No matter how I think about this logic, it seems like a dead end, and its approach contradicts Itachi's character. I've been discussing this with a reader lately.
He told me that Itachi should tell Fugaku about the Nine-Tails incident, and then on the night of the Nine-Tails, Fugaku should lead the Uchiha clan in the fight, thereby changing his impression among the village commoners.
My point is, with the death of the Fourth Hokage, the leadership suspected the Uchiha Sharingan was controlling the Nine-Tails.
Even Naruto, the vessel that sealed the Nine-Tails (a supposed hero), was ignored and condemned as a public enemy.
Even if every Uchiha clan member were dead, a single move from the leadership would make the Uchiha a sinner, forever unjustified.
The only possible solution to the Uchiha issue is to find a leader who treats the Uchiha people fairly in policy.
Throughout Konoha's history, there have only been three such leaders: the First Hokage, the Fourth Hokage, and the Seventh Hokage.
This approach carries its own risks, but it's the only possible solution.
Regardless of whether the Fourth Hokage is trustworthy or not, at least if he survives, the resentment between the village and the Uchiha clan will not deepen as it would later.
In addition, there are readers' responses in this chapter, saying that the source of the information about Itachi's conversation with Minato should be changed to predicting the future.
Predicting the future does exist in Naruto, and the Fourth Hokage is one of the people who knows it best, that is the Great Toad Sage of Mount Myoboku.
However, predicting the future requires a huge amount of chakra, and the predicted future is also very vague.
Itachi knew it so clearly, and it is difficult to explain why he could think of finding the Fourth Hokage through Shisui at his age.
This reason, not to mention that Itachi himself might not be able to think of it, would the Fourth Hokage believe it if he said it?
It would also destroy his character.
Of course, this is just my personal opinion on logic.
If you have different opinions, you are welcome to discuss, but I hope it is best to have mature opinions.
Comment your opinion!
