Eren has no superiors, he carries the founder titan in his blood which puts him at the level of King Fritz.
You attacking me doesn't help your case when it's literally established in canon that Eren can see the future and all of his actions stem from not having other options if he wants Eldians...
Eren is both the commander and the army, he makes the calls and executes them without having to ask for someone's permission. All your complaints stem from not understanding this simple fact.
By the way it's funny how you missed the part where Hizuru only agreed to "ally" themselves with Eldia...
@Baksz are we reading the same manga? Eren's actions are portrayed as necessary and Eren himself is reluctant to do these things but he has no choice since he knows from his future vision that doing any less is going to cause even more casualties among Eldians.
