Mexico proposes that the four nations that constitute the Latin American treaty should sign an agreement that any colonization or occupation of American lands is illegal, and that in such an event, the armies of all 4 nations would unite under a Military Council headed by Mexico, the creator of the alliance. After 4 years, the head of the military council would shift to another country. This is in response to Germany's expansionism in Europe and the takeover of the Falklands by the Axis.
Germany's leader, Adolf Riddler, called the inhabitants of South America an "mixed race" that is full of savages in his book Mein Kampf. In this book he also advocated racism and hostility, even to the point of war and homicide against these "mixed races." This is a warning to all self-respecting Latin American countries... do NOT trust Germany.
Again, any smaller Latin American countries are free to join.
