Board Thread:Theories and Speculation/@comment-38123797-20190118114618

It is common knowledge that Itachi can place someone inside a subtle genjutsu and since, this is a basic genjutsu, he should be able to cast it without eye contact. Breaking a genjutsu is one thing. Since Naruto was able to get out of it easily, I don't think this breaking out of this subtle genjutsu will be a challenge for anyone. But, seeing through the Genjutsu is another thing. The person needs to first realize that he is inside a Genjutsu to attempt to break out.

So, this leaves Itachi with an op ability that he can cast without eye contact and someone who cannot see through it cannot ever escape it.

Is this theory correct?

Also, the people who can see through it even though Itachi casts the subtlest of the Genjutsu will be the Uchiha, someone who has trained his eye like deidera, sensory ninja and someone who has sage jutsu and maybe someone who can detect changes in his own chakra like Sakura or the Hyuga.

Now, apart from the above list, Itachi can use this subtle genjutsu and make the person realize that he is dead and can one-shot Amaterasu from somewhere else. So, theoretically, he can one-shot 8 gates guy and can defeat the five kage all at once, since Tsunade is the only one who can see through it. Where am I going wrong? Because it is just hard to believe what I stated above.
