The title says it all. How do you prevent Spanish America from fracturing after independence and thus potentially becoming a regional economic powerhouse? (Say, with some land reform and a booming export mining industry.)
Furthermore, could Bolivar and San Martin ruled somehow as co-presidents (maybe one in Mexico City and the other in Buenos Aires), or at least have convened a Pan-American constitutional congress similar to the one in the North? How would a new Spanish American Union resolve the issue of federalism vs. regionalism which is shared by the early United States of America?
