I've always wondered something, and is, what kind of goverment did the Earth Kingdom turn into?
We all know that in the last episode, Wu decided that he would abolish the monarchy, that means the Earth Kingdom would not be a kingdom anymre, but, as Wu stated, "decided to abolish the monarchy in favor of democratically elected leaders in each separate state, an idea for which he received the support of Avatar Korra."
So my question is, WHAT did the Earth Kingdom exactly became? A version of the United States of America (in which all states are still the same country, with centralization in Ba Sing Se), or a version of the European Union (different independent states, but with a supranational union, without a clear capital)?
Let me hear your thoughts on the matter.
