Firstly, I must say that I find it rather humorous that this was posted in the future (My computer says it is only the 17th) but time zones make everything complicated.

Now then, during WWII, I doubt the union would have lasted not just because of the Nazis conquering France, but because the two nations are too distinct to form a long-lasting relationship like that.

I won't pretend I know much about the Suez Crisis, but I'd say it would have the same problems as the above.

Prince Louis becoming king of England sound plausible, at least, and whether or not it could last is debatable, and though interesting, I'd say the choice below is even more so.

Mary, Queen of Scots, producing an heir for France and Scotland by the Dauphin, sounds the most interesting, and I would very much like to see an alternate history made of it.
