AoT is a fantastical allegory for a world after WW2, and in that allegory the eldians are the jew-inserts.
The race in-power responsible for the world's ills get overthrown, is systematically cleansed in camps and the survivors kept in small controlled ghettos; only there's no US and Russia to turn the tides so the "Nazis" (Marley) win the war and take over the world. Then a surviving nation of jews become the US-inserts as well by getting the A-bomb before anyone else (The Rumbling) which they use (In AoT, literally reverse-genociding them all) and ensure "global peace" for at least the forseeable future.
