Not sure if this is Captain America or Marvel Knights: Captain America. But I’m pretty sure it’s canon.
It starts with Steve Rogers looking for survivors on the evening of September 11, 2001, at the World Trade Center site. It touches on anti-Muslim prejudice in the wake of 9/11 but mostly has Captain America beating up terrorists (who are Muslim) that attack a fictional American town called Centerville.
They then fight Captain America using weaponized and brainwashed children.
Captain America ends up killing the terrorist–accidentally. He then on purpose reveals his own identity, on camera, out of a sense of needing to take responsibility for his actions.
It’s not that dramatic for me as a reader, though, because it seems like the world always knows who Captain America really is–Steve Rogers has rarely been much of a “secret” identity. But I guess in continuity, right now the world doesn’t know who he is so this is a big reveal.
Yeah, it’s all very obviously analogous to real world events. Rather than make it a better read, the realistic elements make this an…uncomfortable one.
