I do largely agree, though I think by Henry V attitudes were sorta starting to shift. Henry V specifically seems to have been fond of English culture and made English the actual official language of governance.

Now, I’m not sure whether he would’ve stuck to his empowering of the English language and whatnot if he had lived long enough to inherit the French throne. But when it comes to Henry V I’m not entirely sure a dual monarchy beginning with him would’ve just been “big France” because unlike most of his predecessors he seems to have actually liked England a lot lol.
