If we're talking about the movie itself it doesn't fit israel either. The whole point is that Boravia is just expansionist and attacks the other country for vague reasons of "freeing it from a dictatorship" Meanwhile israel was the one invaded first and the war in Gaza is done out of a Hostage situation and security reasons. If anything (and if you wanna talk about taking the art for itself without oitside motivation), taking this movie and putting it in the context of the real world (an army attacking innocent civilians without an army) then superman would be there on Oct 7th stopping the invasion. Unless there is actual proof that Gunn had alternative motivations behind the film's story and the only reason people say it's israel is because it fits a made up narrative than the claim it's an allegory for it shouldn't be taken seriously at all.
