[Firefly] What would the Alliance do if they ever encountered intelligent alien life?

What would the Alliance do if they encountered intelligent aliens that were:

**Possibility One** - relatively primitive and lived on a single planet without space travel.

**Possibility Two** - at about the same level of advancement as the Alliance.

**Possibility Three** - much more advanced.

If the peaceful primitive aliens lived on a world with resources valuable to the Alliance, it's likely that they'd exterminate the species without letting the general population know. And then they'd aggressively harvest said resources. If the world has nothing they want, the Alliance would probably announce its existence to the public and deem it a "nature preserve" to show just how benevolent and awesome humans are. Nobody would be allowed to colonize it, but scientific expeditions would be common.

It's similar with relatively similar advancement. If their home territory has something the Alliance needs, it WILL lead to war. The Alliance may stage things to make the aliens look like aggressors, or publicize the conflict as a struggle for humanity's survival. If they don't have anything... it would still eventually come to war. If the government thinks the people need a war for whatever reason, the aliens would be convenient scapegoats. 

If the Alliance is completely outmatched, they'd try to avoid as much as possible just in case the aliens turn hostile. (Or if the aliens realize how tyrannical the Alliance is and want to "liberate" the people.) They would also try to hide the truth from the population as best they could, lest any stupid humans try to contact the aliens and spark a conflict.
