The failure of Vietnam could be laid at the door of American foreign policy but the decisions that led to the failure were made by presidents aware of the risks, clear about their aims, knowledgeable about the weaknesses of their allies, and under no illusion about the outcome.

The book offers a picture of a steely resolve in government circles that, while useful in creating consensus, did not allow for alternative perspectives. In the years since its publication, The Irony of Vietnam has come to be considered the seminal work on the Vietnam War.
