This study of playbooks was completed in the last days of President Donald J. Trump's first administration. As a consequence, the final result of Trump's playbook to get reelected is not known. This history provides a comparison of how both Hitler and Trump achieved their goal of attaining or maintaining power through a playbook and in the case of Trump it can predict his future actions. The book is based upon the works of scholars but more important are the first-hand accounts of people closely associated with these principals such as Heinz Guderian, Hitler's Chief of the General Staff and his personal secretary, Traudl Junge. First-hand accounts of Donald Trump during his presidency are provided by John Bolton, Trump's former National Security Advisor, James Comey the former director of the FBI, Mary Trump his niece and others. The books written by Donald Trump and Hitler are key sources in identifying their playbooks.
