} No, they annexed it.
} As you don't know, back in the days of Napoleon III, France controlled
} Mexico. When the United States Civil War ended, Napoleon withdrew
} his troops from Mexico, leaving Maximilan floundering and eventually
} foundering there. But although he (Maximilian) was killed by the
} republicans, who came into de facto power, they never regained de
} jure power. This is because of the 1859 reform laws, which were still
} in effect (according to the republicans). You see, the reform laws,
} which were designed to separate church and state, included clauses
} designed to prevent the takeover of the government by a high church
} official. One such law was so badly worded as to inadvertently make
} the death of Maximilian and the consequent takeover of the government
} by the republicans illegal according to the republicans' own laws,
} so that Maximilian's heir, Augustin III, actually became rightful
} ruler of Mexico (just as he claimed).
} Fast-forward to 1940. The Third Republic had been in place in France
} for many years, but, unbeknownst to France, it never relinquished its
} official hold on Mexico. The ruler of Mexico was now Empress Maria
} Josepha (as she called herself and as she was, though most people
} called her Princess Maria).
} Then, in June of 1940, Germany and France signed what was called the
} Second Armistice at Compiegne. It stipulated that 60% of mainland
} France go to Germnay, along with all overseas possessions. Now,
} Germany never did anything about those possessions, but it technically
} annexed them.
} In May of 1945, Germany surrendered to the Allies. The preliminary
} divvying up of Germany's land had been done at the Yalta Conference
} in February, but it was finalized in June of 1945 with the Potsdam
} Agreement, which listed all the lands that Germany had annexed or
} owned -- including Germany itself -- and what was to go to whom.
} But the list was not all-inclusive, as no one realized that Germany
} now owned Mexico. Now, by long-standing international custom, any
} lands not claimed by the victors remain in the possession of the one
} who lost the war. In this case, Germany retained possession of Mexico.
} When the land of Germany was occupied (1945 to 1949) per the Potsdam
} Agreement (and so were other possessions), Mexico was not. Thus, even
} though there was no German government with any power, the country of
} Germany lived on, with practical existence only in its territorial
} possession of Mexico. When the countries of East Germany and West
} Germany were created in 1949, West Germany inherited all of the Third
} Reich's possessions (i.e., Mexico) by the terms of the Grundgesetz.
} And modern-day Germany, of course, is just a renaming of West Germany
} after it annexed East Germany (a voluntary annexation).
} So there you have it, Supplicant. Germany annexed Mexico back in 1940,
} and retains it to this day, which explains the music.
} You owe the Oracle a bratwurst enchilada.
