Of course; sorry if it came off jackassish, i was in a hurry.
it's just that England has a history of meddling in Scotland; there was a frothing hatred between the two countries at times, and Scotland had a traditional alliance with France.
Now France is part of the dynasty that has spent a few decades trying to conquer Scotland. Err, that's not good.
Of course, the French half would be more interested in the low countries and so forth, but there's no reason that the Plantagenets in Paris couldn't focus on both. The Valois dynasty could focus on different places, of course.
Of course, I don't think an english conquest of France for decades is particularly plausible. The duke of bedford, who was regent in France after Henry V's death, was very competent and a damn good general. Even he had trouble; there weren't enough Englishmen to go around. The high tide that England reached was largley do to the Burgundian rift with the Valois. Once the Burgundians switched sides in 1435, the English position collapsed.
A more succcessful England is possible, of course. If charles VII dies in 1422, the French cause is shot. I can't see any potential claimants after him, so Bedford wins by default.
But... the king of England is insane. Once that happens, things in France are going to get messy, as especially as southern Frane is never likely to be particularly loyal. We might see the house of Savoy lead a resurgence in the Kingdom of the Arelate, or perhaps the Swiss take Lyons.
With an insane Henry VI, and the English position in France being chaotic, Phillip the Bold might exploit the rift there. Why fight for the crown of Lotharingia when he could be King of the Franks?
