This blog analyzes the manga, so it focuses on the content included in it. Whatever politics is included in canon is what I cover. Hetalia isn’t historically accurate so it personally doesn’t make sense to me to analyze their relationships in relation to the outside world without any canon material relevant to it.
I know it’s a bit weird to grasp, but Hetalia is fiction that brings in real-life elements. The Hetalia universe is a separate reality essentially, drawing on whatever Himaruya decides to include from the real world.
