8This book introduces first hand witness and whistleblower testimonies revealing that the USA, Britain, Russia and other major national governments have been secretly conducting, or known about, diplomatic relations with different extraterrestrial civilizations since at least 1952. Galactic diplomacy (aka 'exodiplomacy') with extraterrestrial visitors began with discussions over the development of thermonuclear weapons, the first of which was detonated by the Truman administration in November, 1952. Diplomatic discussions then expanded to include issues such as technology development, alien bases, extraterrestrials living on Earth, human rights, and use of earth resources. In frustration over lack of government transparency with their citizens, some extraterrestrials began contacting private citizens to inform them of the true nature of alien activities on Earth, and relations with governments. The reader will be introduced to the basic principles of international diplomacy and how these apply to different extraterrestrial civilizations visiting Earth. Those desiring to expose secret government activity in diplomatic relations with extraterrestrial life, will be given the necessary information to hold responsible government, military and corporate officials accountable for past policies; and to ensure government transparency in the future. Alternatively, those desiring to become active in citizen diplomacy initiatives, will be given essential information for discerning the motivations and activities of visiting extraterrestrial civilizations. This is indispensable for practicing a citizen based form of galactic diplomacy. This book prepares readers for the grandest adventure of all - the journey to galactic citizenship!
