 The Federation apparently had the mightiest military force in the galaxy and it used the threat of invasion to intimidate non-aligned worlds.Occasionally the Federation might employ more subtle methods of taking over worlds, such as installing puppet governors under their control, supporting revolutionary forces loyal to their cause, and inciting wars between worlds by manipulating delicate political issues.In the latter case, if war broke out between worlds, the Federation would enter as a neutral arbiter and peacekeeping force making it easier for eventual take over.
