A historically accurate Steve Rogers would have never put the uniform back on in the 20th /21st century and instead became a Maoist third world-ist.

Facts, his parents were Irish immigrants to New York in the early 20th century. At the bare minimum that means fleeing English colonial genocide and at the most possibly Irish Republican and socialist sympathies. His mother was a seamstress in New York, an often unionised and radicalized occupation due to events like the triangle waist factory fire.

Steven was such an anti-fascist that he wanted to fight Nazis in 1941 before the USA had joined the war. He then fought Nazis all over the globe, alongside the USSR (and even saved Stalin’s life). He then went into the ice in 1945, missing the USSR being made the villains in the Cold War and the US recuperating the Nazis in the GDR and with operation paper clip.

And due to the sliding time scale even more USA war crimes happen before he comes out of the ICE (roughly always 1-2 decades ago).

noooooo my Cap punching Hitler
