How America responded to North Korean-type threats in 1940

…here was an American superhero punching the leader of a sovereign nation in the kisser. Subsequent issues kept pitting Captain America against Hitler and his goons.

The angriest reaction came from the German-American Bund, Hitler’s stooges in the U.S. They harassed Jack Kirby and Joe Simon, the creators of Captain America, with hate mail and telephoned death threats.

[…]

Simon called the cops, and as soon as the police showed up, the phone rang. Mayor Fiorello La Guardia wanted to speak to the creators of Captain America. Simon got on the line. “You boys over there are doing a good job,” the voice squeaked. “The city of New York will see that no harm will come to you.’”

That is how it’s supposed to work in a democracy.
