So, I know this isn't the intent of this map, but the effort for multiple canal zones like that is crazy, especially the Costa Rican one which seems to go straight through a mountain range.Courtesy of u/Sp4g00ti from Reddit: a Mexican-Philippine propaganda poster, commissioned during the War of the Nicaragua Canal.
Due to the Louisiana Territory never being sold to America, Mexico inherits a much larger amount of North American territory. Additionally, the Philippines revolt and break free from Spanish rule. However, they are weak and divided, so they turn to Mexico to protect them. Through the 1800s, Mexico takes the role of OTL America and becomes much richer due to trade with Asia. Meanwhile, the US loses the War of 1812, leading to an early Civil War in which the Confederacy wins.
Fast-forward to the time of this map’s making: France has occupied Nicaragua (part of this bigger Mexico) as they wish to build a canal there. Mexico retaliates; Britain chooses to join France. The CSA opportunistically invades across the Mississippi. Faced with this threat, Mexico commissions propaganda posters to convince the Filipino people to take up arms and sail across the sea to take on France, Britain, and the Confederacy. This map is an example of one of those posters and depicts a worst-case scenario, similar to OTL's over-exaggerated WWI propaganda posters. Notably, this shows a weak United States being carved up alongside the actual territory of Mexico and the Philippines (despite the USA not being in the war).
Red lines are pre-war borders. Italicized words in parentheses mark the “demands” of the Allied powers. Words in quotation are mostly sentences taken out of context to exaggerate the allied war aims.
I really like the concept and absurdity of it, but it is also hard to figure what the ITTL situation is. It looks like New Amsterdam is an ally?
