Professor Rummel's work, Death By Government, is a product of eight years of research into the roots and causes of Democide - defined as the intentional killing by governments through genocide, politicide, and arbitrary mass murder of its people. The cornerstones of current U.S foreign policy - centered around fostering democratic freedom - are based upon Professor Rummel's correct observation, that liberal democracies promote the greater peace and they are essential to eliminating Democide and ending wars between nations. Through empirical research the evident truths become exposed and the reader is left with the overall understanding that absolute power corrupts and leads to the murder of a governments' people and that only through restricting and checking power can these horrors be restrained. Democracies virtually never make war on each other and the more democratic two governments, the less the likelihood of violence between them. So not only is democracy a solution to domestic democide, but globalizing democracy is also a solution to war. The existence and spread of liberal democracies (not just electoral democracies, but liberal democracies in terms of civil and political rights and liberties) provides the long run hope for the elimination of democide and war. Professor Rummel astutely notes that power's relationship to democide is on a continuum - the more absolute the power, the more democide. The problem is Power. The solution is democracy. The course of action is to foster freedom.
That America actively supports dictatorships is well-known. I wonder if this book includes genocide of Native Indians.
