In recent years there has been a move towards 'Disclosure' of the interaction between non-terrestrial intelligences and people on earth. There are now organisations established to develop the politics - or 'Exopolitics' - of this liaison and the implications in managing such affairs. I would suggest looking at two of these organisations:
Another organisation worth looking into is the The Society for The Greater Community Way of Knowledge:
THE ALLIES OF HUMANITY is being presented to prepare people for a whole new reality that is largely hidden and unrecognized in the world today. It provides a new perspective that empowers people to face the greatest challenge and opportunity that we as a race have ever encountered. The Allies' material contains a number of critical if not alarming statements about the growing intervention and integration of extraterrestrials into the human race and about the aliens' activities and hidden agenda. Instead of providing "hard" evidence about the reality of alien visitation to our world, which is already well documented in many other fine books and research journals on the subject, the Allies material, as it is known, addresses the dramatic and far-reaching implications of this phenomenon.
The source of this information describe themselves as physical beings from other worlds who have gathered in our solar system near the earth for the purpose of observing the communications and activities of those alien races who are here in our world interfering in human affairs. The source refer to themselves as the "Allies of Humanity." The Allies' stated purpose is to alert us to the risks of emerging into a Greater Community of intelligent life and to assist us in successfully crossing this great threshold in such a way that human freedom and self-determination can be preserved.
