"All of Marvel's new heroes of the early 1960s some how reflected and contributed to American perceptions of its Cold War enemies, but none more explicitly than Iron Man, whom historian Bradford Wright identifies as "the most political of Marvel's superheroes" (222). Reflecting back on some of his co-creations in 1975, Stan Lee dubiously claimed that "Marvel Comics has never been into politics" or beholden to an "official party line" before offering a near-apology for the moral simplicity of the portrait of the Vietnam conflict in 1963's "Iron Man Is Born!" (Son of Origins 47.) A disinterested observer would find much evidence to counter these claims in the pages of Tales of Suspense between 1963 and 1968."
