In this story, Superman is the antagonist, go figure, and the world is saved by the benevolent capitalist Lex Luthor, who uses the ultimate liberal move (a strongly worded letter) to beat Superman, which ushers in a golden age that ends in the destruction of Earth. Kind of an unintentional self-own.
Also the Batman of this universe is coded as an anarchist and has a tattered American flag hung in his Siberian batcave, like all anarchists.
