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

So the English had a proto-English Identity when the French didn't is your. What in history sustains this claim? The first document in French is the treaty of Verdun (845) so we had a vague idea that the language exist, so at least, the Franks didn't speak any more a Germanic language.

Yeah I'm not touching this point, I dont really care much whose nationality came first, PVC and Gilrandir can argue this.

In the Battle of Bouvines, in 1214 Phillip II August is the King of France and the Knights serving in the French Ost recognised themselves as French.
In the battle of Bremule (1119), Henri VI the Fat is describe by the chroniclers as the King of France, and is recognised as such by Henri I, Duc of Normandy and King of England.

These examples are of the french nobility, not the pesantry. Which is the point, all Henry had to do is win a succession war and kill or evict any French nobility that wouldn't kneel and the pesants will fall in line.

Whereas Henri V would have been able to defeat the French is another story and we will never know. I doubt it as he employed tactic which became obsolete, the same methods use by his successors. The final French victory didn't came from the English lack of courage or will, it came from the French King creating a first national army (it is said that the 1st Infantry Regiment is the heir of the Bandes de Picardie, France created at that time, taking model on the English but including artillery, a weapon the English knew about it as they were the first to employed, but too confident in the long-bow tactic, put aside.

I say that if Henry was around to press his claim after Chales the Mad died england would have been strong and uninhibited by infighting and thus France would have been won before the longbow was countered.
