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.

The shape of the world as it is now and has been
Format: Hardcover
I am currently reading this book. I am a specialist in political science, history, Latin American studies and an "old guy" now, born just post-WWII. This is in a long life of study and research and living in three countries--US my birth country and two very different Latin American countries, just for context. I can simply and unreservedly say that this is one of the most important books I have ever read. Not only interesting to read for any caring person, but absolutely requisite.
