In The Captains and the Kings (1976) Caldwell takes on the global power brokers. In this book we find, running through the story line, a description of the way the international financiers and industrialists (all private consortiums owned by an elite of the world's richest families and persons) hijack governments around the globe; instigating wars and gaining control over the warring countries through manipulation of the enormous debts incurred during a war. Mentioned too is the Council on Foreign Relations; and while a disclaimer states that all persons portrayed in the book are fictional, it is clear that the Council on Foreign Relations, as well as another major organization of the globalists are both very real organizations. Also described is the idea that political systems everywhere, and certainly in the US, are almost totally dominated by the ruling elite; and that no one even gets into the running for a major political office unless the elite believes the person is under their control. It is explained that this can be direct control; e.g., the candidate takes a solemn oath to be true to that organization above all others; or indirect control: the candidate is known to have done something illegal or scandalous. The threat of public exposure can then be used to bend the person to the will of the elite. Politicians can also be compromised through a "set-up". When necessary the elite will play that hand (conform or be ruined by the controlled media). It is further explained that there have been a few who were not under the control of the elite (back in the 40s and 50s) and who had some success on their own. These individuals were not corruptible and in such cases very dirty tricks were employed against them. There is a figure in the book obviously symbolising JFK, who went along with the elitists, (his father's cronies) but who once in power went his own way - resulting in his assassination.
The Captains and the Kings was made into a TV mini-series - which avoided all the serious implications of the book and concentrated on being a predictable sex and drama story.
