The Post-Apocalyptic Roadmap/Mexico
Part of the Post-Apocalyptic Roadmap Project.
All I can say about this project is FUCKYES. I'm going to do Northeast Mexico.
Back in the old days the Soviets had the 3 biggest Mexican cities (Mexico City, northern Monterrey and western Guadalajara) as nuclear targets in case the US government faced a wasteland scenario in their homeland and decided to relocate most of their fighting forces as well as strategic commanders.
In a scenario such as this, it stands to reason that at least two of them would face nuclear strikes.
Imagine Mexico City's whopping 22 million people facing one nuclear strike. The CHAOS... :)
Furthermore, since our Armed Forces haven't seriously participated in a single Int'l war (WW2 Escuadron 201 notwithstanding) since the French Intervention of 1880's they don't have real military capabilities but have become quite the internationally recognized experts in disaster rescue missions (hurricanes, earthquakes, etc.) and internal repression of the populace.
You rock, OP.
