In 2018, Mexico commemorated the 156th anniversary of the Battle of Puebla, where a smaller Mexican force defeated French troops in one of the most iconic battles in Mexican history. Ironically, this celebration coincided with another significant event related to Mexico and its northern neighbor: the ongoing debate about building a wall separating the US from Mexico proposed by former President Trump. While both events felt like polar opposites - one represented unity against foreign invasion while the other signaled division between two nations- they share something in common: they illustrate how historical events can shape our present and future relationships.
