Here is a another thought about the "power and responsibility" theme developed most explicitly in the Spider-Man stories of the 1960s. Spider-Man and the most of the rest of the Marvel Universe were products of the Kennedy-Johnson era, and while we remember that as a time of great liberalization in domestic policy, it was also the Cold War's deadliest phase. Just as Spidey was debuting, American leaders launched a massive military campaign, costing many thousands of American and Vietnamese lives, to prop up a corrupt, unpopular government (and thwart of the completion of the country's anti-colonial revolution) in the name of saving a faraway land from the evils of communism. I am referring to the escalation of the U.S. war in Vietnam. Were the new superheroes of the 1960s part of the same mentality? Was the superheroic ideal really altruistic and self-sacrificing or just a self-serving and self-deluding excuse for getting our way by force?
It may be helpful to compare and contrast Spidey's "power and responsibility" mantra with the more explicitly Cold War-oriented Green Lantern Oath.
