Yes, the US is in fact made of many different nationalities, but don't tell me there's not a much greater identification with the UK than literally any other European country, not only linguistically but culturally, but the language is really the main thing. Language isn't just a tool, there are tons of things transmitted through it, it's why Shakespear is idolized and almost deified as opposed to any number of other european playwrights or authors, be they german or french or russian or what have you. They wouldn't self-identify so greatly with the past of another nation otherwise . I've been to the sad sorry excuse for what passes as public schools in the US, heck I've spent half my life in the US, I feel my utter disgust for blatant jingoistic bullshit is justified given that I have personal experience of it.
And there's literally dozens of examples of outnumbered forces triumphing in the face of great adversity during the middle ages, so why Midway? It's a deliberate attempt to link two incredibly dissimilar battles, from two incredibly dissimilar times and with dissimilar outcomes. Again, the one thing you could say about them is that they were both won by a side that spoke english.
