Its purpose is to dissuade white males from violently overthrowing the elites.
Its purpose, as with the source material, is propagating the anti-war sentiment (pacifism). The international war in the film did end with "white males" (including mutinying soldiers and especially military sailors) overthrowing "the elites" (Kaiser himself fleeing into exile). It's just not shown, as the protagonist is killed in October 1918. And the new film, unlike the previous version, does show the politicians: https://youtube.com/watch?v=hf8EYbVxtCY
