The Anglosphere is the only thing that keeps the world from descending into barbarism

Castillion happened several decades after Henry died.

Ultimately the treaty doesnt matter beyond giving the English kings a higher degree of legitimacy to thier claim, if the French lords refuted it there would have been another war and by his previous record I do believe that Henry V could have won that war too.

I believe that if henry had lived long enough to actually get the crown and bring up his kid properly his dynasty would have had a proper chance of cementing thier rule over france.
