In "The March of Folly: From Troy to Vietnam," Barbara W. Tuchman explores the concept that once a misguided action is set in motion, the weight of that momentum can often make it more challenging to reverse course than to continue down a path of folly. This suggests that individuals and societies may persist in poor decisions, driven by a reluctance to acknowledge errors or change direction. Tuchman illustrates this theme through various historical events, highlighting a tendency to ignore reason in favor of maintaining an established course.

The quote, "Awful momentum makes carrying through easier than calling off folly," encapsulates the struggle faced when confronted with the consequences of misguided choices. This idea reflects not only the psychological aspects of commitment but also the societal pressures that lead to the persistence of failing policies or actions. Ultimately, Tuchman's work urges readers to consider the importance of wisdom and foresight in decision-making, emphasizing that recognizing folly can often be the first step toward corrective action.
