In the Greater Community, the advancing race of any solar system is considered the master of that solar system and rarely will outside intervention occur. History has proven that the conquest of one race over another is too costly and too destructive. There are more subtle ways to influence nations and in this, the development of skill in the mental environment has been the great emphasis for those who are interested in conquest and acquisition. Brute force is too destructive, requires too much effort and often produces unwanted results. This is a lesson that advanced worlds have learned.
