The author Michael Wolff discusses a critical aspect of Donald Trump's decision-making abilities. He points out that the main problem is not Trump's potential for reckless actions due to ignorance of their consequences. Instead, the challenge lies in his inability to fully grasp the necessary options available for action. This lack of understanding significantly hampers his capacity to make informed decisions.

Furthermore, Wolff illustrates that Trump struggles to remain focused long enough to evaluate the choices in front of him. This mental fog affects his leadership, as it obstructs him from taking decisive actions even in urgent situations. The metaphor of the "fog of war" conveys how this confusion interferes with his command capabilities.
