In order for political satire to work in a map, all the political issues and current events involved of a given world would have to be known by the viewer to be understood.
Any slice of history in the known world - our world would work, as in the sample map shows. It could work for say Middle Earth, as most people are somewhat familiar with the geography, as well as what's going on in Mordor, Minas Tirith and Rivendale.
It wouldn't work for my Duchy of Dernallion unless you understood my campaign world, its politics, mythos and current events.
Although it might work for an island shaped like a cat-dog thing!
