[Aliens] Why are alien planets *always* unified politically?

Every time I see a sci-fi in which another planet is shown, there's always just one government ruling the whole planet and no other political divisions. Given that has never happened in the history of the earth, why do we assume that it'd happen on other planets? Any examples of a sci-fi alien planet that has multiple nations on it?

In startrek most races have conflicting political parties. That being said they still act in unison for the most part when attacked by outside forces. An example of this would be the Klingons. They have a consul of honorable families that have power and there own political goals.  That being said most scifi that deal with aliens race seem to assume that by time you are capable of FTL travel you have created a society that can at least unite your planets political parties.
