Regarding the Japanese interpretation of the allegory -- I don't think it's apologist toward fascism really, because essentially every side in the conflict has fascist elements. In that sense, it's more "some situations just don't have any good solutions." But what's clear to me is that the situation itself has fascist roots. Regardless, the Polygon article in question has a much more surface-level reading -- it is clearly stating that it's antisemitic, which I simply can't see at all.

I don't understand what I'm looking at with the site you linked, but I am intrigued.
