So glad you liked the end! As I think I mentioned last week, this was my favorite of the Narnia books as a kid and a lot of it has to do with what you just described about what was satisfying about the end.
I love your point about politics because it is so unusual to have a geopolitical conflict in a Narnian novel (in some ways--this makes it closer to the Game of Thrones verse!). And it sounds like you're connecting this too to the global wars that Lewis would have lived through, which is an interesting idea as it suggests that one of the things this particular novel is concerned with is a celebration of allyship.
