I'd integrate with the enemy. Subvert their beliefs taking as much time as needed. I would work to synergize people like me and work to build protectionist systems that would be used to further our agenda using all available tools to subvert those not considered to be of the same origin.

I would produce endless propaganda used to project thought where I want it. People would believe that my group needs special attention and must be saved. We are the ones chosen of god. Surely all lesser humans would be happy to be enslaved by the systems I create.

I would seek to maintain control of resources and exchange means. I would take leadership of all things and form groups of my people everywhere.
