An admiring but not uncritical portrait of a titan in the rule of law
Format: Hardcover
Professor White delivers an admiring but not uncritical portrait of a man who stood for qualities and principles now in short supply. Jackson was a leading practitioner when other judges were more political, but nevertheless had to speak the language of the rule of law. And his contributions at Nuremberg, haphazardly portrayed in the recent movie, really come through . The United States would help establish a record of epic misdeeds and show that the perpetrators could be punished in a system of justice.

Comprehensive and compelling
Format: Hardcover
With this volume, Mc Coy firmly establishes himself as a historian whose far sightedness only improves with age. A robust story teller, he demonstrates an uncanny ability to ferret the secrets out of arcane documents and records and connect the dots into a compelling narrative. Here he shows how the best and worst of political and military strategy in the US and the other cold war powers shaped the course of global events in profound ways. The lessons for us today simply leap from the page. This is a must read for any thoughtful observer of today’s world.

Brilliant until last two chapters
Format: Kindle
A riveting well researched deep dive into the cold war up through the 1980s. The later chapters following the collapse of the Soviet Union seem to have been hurriedly written and only superficially cover events, particularly so as relates to Russia.
