In most AH scenarios where France goes to war with Germany, Great Britain, or pretty much anybody in the latter half of the 19th century or first half of the 20th century, it seems that even if Alsace-Lorraine, Picardy, and Brittany are all stripped from the country, it will, more likely than not, still retain Algeria. Why? Surely it would make sense for the territory to be passed on to Italy or Britain or Germany in the case of a harsh peace with France, but I rarely see this happen.
