Hey, I just started with this idea i've been trying to develop for the last few months, and I would like opinions on it, as I'm new here and this would be my first AH work.
This idea is about a near future where a revolution erupts in México in the year 2013, leading the U.S. and it's allies to intervene on the rebel side, hoping to reestablish democracy in México after a short but brutal dictatorship. So, they spend significant resources on this war, leaving them unprepared for a combined Russian-North Korean-Chinese-Iranian invasion. The President of the United States is killed a short time after the war in México was won by the rebels and their leader quickly elected President of México. With a rapid shock-and-awe campaign in the U.S., the invaders occupy the country. This leaves American troops still stationed in México without leadership. Having had fought alongside the new Mexican President in the war, they had come to respect him for his leadership and his strategic, operational and tactical skills. With no leader, the defect to the Mexican President, who then leads a combined Mexican-American army into the U.S.
So basically the invaders start facing their own serious internal problems and they have to pull back most of their forces, leaving the Mexican-Americans free to brush aside the few troops that stayed. So it goes around that way and soon the whole American people, along with the Mexicans, start worshiping and acclaiming this new leader who eventually crowns himself "Emperor of México, King of Louisiana-Mississippi, King of Florida and King of New York".
Im also thinking about developing this alternate world into one were people all over the planet start losing faith in republics after prolonged warfare and chaos, and slowly turn back toward monarchies, hoping a single, strong sovereign will protect them and their nations, something like what happened when the Roman Empire fell and feudalism arose soon afterwards. Im thinking about an Empire of Canada, an Empire of Brazil, a United Kingdom of the Antilles, a Kingdom of Valparaíso, a Kingdom of Araucanía, an independent Kingdom of Siberia, and events like a War of Hellenic Succession and a Siberian-Alaskan War.
So please tell me what do you think of this, give me your constructive criticism, your suggestions and anything you would like to say
