In one of our various irregular series, Matt's going to be taking a look at the history of Mexico and U.S.-Mexican relations through time. These eps are going to feature Matt with some guests in conversation, starting with our 19th century All-Star Matt Karp. Matt and Matt are talking about the U.S.-Mexico war, which, if you've listened to Hell of Presidents, you'll know is (at least here in the states) a kind of under-discussed foundational moment in all of the rest of our shared histories. They discuss the motivations for the war, the Mexican political perspective, the course of the conflict, root beer, the Irish, death by diarrhea, and much more.
