RISK

Readers may assume that the Army has no problem taking risks, but McChrystal, a retired four-star general and commander of U.S. forces in Afghanistan, emphasizes that the opposite is true: “to the very marrow of its bones, the United States military is an intensely risk-averse entity.” Charged with defending the nation, the armed forces cannot fail, so “most military leaders prefer belt and suspenders, and a backup set of each.” Yet, despite full knowledge of a threat, the military has been caught by surprise in disasters from Pearl Harbor to 9/11, and civilian leaders have dithered in confronting crises such as Covid-19 and the aftermath of Hurricane Katrina. McChrystal emphasizes that organizations and individuals fall victim because they focus on the probability of something bad happening (and, if it’s unlikely, paying little attention) instead of what they must do about it. As a solution, the author presents the “Risk Immune System,” a process similar to our body’s defenses against infections. An efficient Risk Immune System detects threats, assesses the risk they represent, and responds. Readers will learn this in the introduction, but these pieces represent only the tip of the iceberg. McChrystal follows with 10 key dimensions essential to his strategy (leadership is “the indispensable factor”) and then a series of solutions to reinforce individual skills and collective collaboration. This is more information about risk than most readers need, but the author lightens the load with a steady stream of stories illustrating disasters (and the occasional success) from history as well as his own experience. A career military officer who rose to the top of his profession, McChrystal has spent a lifetime dealing with risks. While his insights seem directed at fellow officers or business executives, average readers will enjoy the anecdotes (mostly about war and business) and have no quarrel with his advice.
