The first thing you need to recognize when you are reading an English translation of Sun Tzu’s The Art of War is that you are dealing with what former US Defense Secretary Donald Rumsfeld called “known unknowns”. Scholars are not certain about when the book was written (estimates range between 770 BCE and 221 BCE), whether it was written by one or several authors, and what motivated the author(s) to write the book.

The Korean War began 70 years ago. In the United States, it is known as the “forgotten war”. Not so in China. In his new book Attack at Chosin, Professor Xiaobing Li, a prolific historian who teaches at the University of Central Oklahoma, and who once served in China’s People’s Liberation Army (PLA), explores the Chinese Army’s second offensive against US, UN, and South Korean forces at the Chosin Reservoir during November-December 1950.

The title of Roberto Carmack’s book is a bit misleading, as is the book’s cover, which shows two helmeted and uniformed soldiers in battle. The book is part of the Modern War Studies series, but its focus is on the administrative, institutional and ideological aspects of war in the Kazakh Republic of the Soviet Union during the Second World War. It is more sociology than military history.

In an age of microchips, information and cyber warfare, precision-guided ballistic missiles, satellite communications, advanced robotics and artificial intelligence, does a book about the historical struggles between insular sea powers and continental land powers have any relevance? Is there any practical benefit—other than an interest in history—to read about how the Athenians, Carthaginians, Venetians, Dutch, and British constructed and utilized sea power? Does the sea or land-oriented “culture” of a country really matter in 21st century geopolitics? 

Geopolitical analysis is partly based on geographical perspective. Writers on geopolitics tend to view the world from their home country’s perspective. Australian national security expert Rory Medcalf in his new book Indo-Pacific Empire uses classical geopolitics and an understanding of modern geoeconomics to survey the current struggle for power in the most contested and consequential part of the world. And he does this from an Australian perspective—an Australian, moreover, whose diplomatic postings included India. That said, his book is a tour de force of 21st century geopolitical analysis that should be read by strategists and statesmen throughout the region and the world.
