I think the best thing would be to ask to be put in touch with whatever governmental body oversees our party of the galaxy and (hopefully) will protect our rights. If there are no rights, then we're screwed either way because anyone that can travel to us will completely out-class. On the other hand, if we can reach the Shadow Proclamatino of Judoon (or the equivalent) we may be granted some form of protection. Hopefully, this protection will take the form of David Tennant.

This will just cause the evolution of undetectable people who will then topple the Empire.
