Okay, this is from a Marxist source but it's an amusing idea. And...yay! I was born in the LP territories, so sign me up.
(Here's where "New France" would be, btw)
Our organization, the Louisiana Purchase Return Committee has been formed to facilitate the return of the Louisiana Purchase to its rightful owner France. Research shows that neither President Jefferson nor Napoleon Bonaparte were authorized to acquire on the one hand or to sell on the other the Louisiana Purchase
.
We demand the immediate return of the States of Louisiana, Missouri, Arkansas, Iowa, North and South Dakota, Nebraska and Oklahoma to our true Fatherland-- France. We also maintain that all so-called American citizens living in the LP are actually, by right, French citizens.
There are many benefits to be gained by the population of the LP having their land, illegally sold by Napoleon, returned to France and their rightful French citizenship restored to them. For example-- they will have a better system of health care as French people. Everyone will be covered by medical insurance and will have affordable prescriptions as well. In addition high quality French wines will be readily available for consumption, replacing the California swill that passes for wine in the American occupied LP.
...The LP states will all become overseas departments of France with all the rights of French people. This means a more democratic system than they now live under. Presently they are subject to "red state terrorism"-- their science text books have nasty little stickers put in them attacking evolution and their public officials are elected in undemocratic winner take all elections, As French people we will have proportional representation and dozens of parties to choose from-- all will represented in the Parliament in Paris.
Okay, you Americans - out of my country, stat! And take Bush with you.
