There is absolutely no way in hell that scene wasn't intended by someone (be it the writers, producers, Godot, whoever) to thumb their nose at critics of the IDF and Israeli Government. It hardly even comes off as feel-good pro military propaganda, it feels like a sneering joke at the idea of shooting missiles at children.
Sure plenty of people may not have thought anything of it, but there's no way in hell that that very specific imagery got put into the movie in such a random seeming way without some intention behind it.
Imagine if you had a superhero movie with a lead actor who's a known Jihadist where the hero is trying to save a plane, steers it toward a massive pair of twined high rise buildings, smiles at the camera, then veered the plane off at the last second. Literally no one here would be denying that that would basically mean "Haha 9/11 lol".
... yes?
Like, that's what being in an army means. You're trained to be absolutely obedient to the military/political interests of a state and therefore you have some culpability for how those interests are pursued.
This doesn't mean that literally everyone in an army should be punished because one person committed an individual warcrime. Obviously people join armies for various reasons and have various degrees of awareness of their state's crimes. But you still share some of the responsibility by definition. Especially if you actively support said army.
It does not.
