Elected with no clear public mandate, George W. Bush achieved surprising legislative successes in his early months in the White House. Following September 11, 2001, his public support rose to unprecedented heights. Actions taken in the following months and years have revealed the exceptionally ambitious nature of the Bush presidency.

High Risk and Big Ambition brings together leading presidency scholars and journalists to assess the trajectory and character of Bush’s time in office. The common theme running through their contributions is that this presidency is best characterized by a series of bold political and policy risks in the service of two primary goals: the transformation of American foreign policy and the creation of a lasting Republican dominance of domestic politics.

Included are discussions of foreign policy, national security, the war in Iraq, Bush’s leadership style, religious politics, and economic policy. George W. Bush emerges as an "orthodox innovator" who skillfully deploys both personal politics and the power of his office in an effort to complete the conservative governmental agenda initiated by Ronald Reagan. Yet because of the size of his ambitions, each success sets up a greater risk of failure. That alone makes his presidency one of the most interesting and consequential in decades.

Just as famines and plagues can provide opportunities for medical research, the unhappy course of United States relations with Vietnam is a prime source of evidence for students of American political institutions. How Presidents Test Reality draws on the record of American decision making about Vietnam to explore the capacity of top government executives and their advisers to engage in effective reality testing.

Authors Burke and Greenstein compare the Vietnam decisions of two presidents whose leadership styles and advisory systems diverged as sharply as any in the modern presidency. Faced with a common challenge—an incipient Communist take-over of Vietnam—presidents Eisenhower and Johnson engaged in intense debates with their aides and associates, some of whom favored intervention and some of whom opposed it. In the Dien Bien Phu Crisis of 1954, Eisenhower decided not to enter the conflict; in 1965, when it became evident that the regime in South Vietnam could not hold out much longer, Johnson intervened.

How Presidents Test Reality uses declassified records and interviews with participants to assess the adequacy of each president’s use of advice and information. This important book advances our historical understanding of the American involvement in Vietnam and illuminates the preconditions of effective presidential leadership in the modern world.

"An exceptionally thoughtful exercise in what ‘contemporary history’ ought to be. Illuminates the past in a way that suggests how we might deal with the present and the future." —John Lewis Gaddis

"Burke and Greenstein have written what amounts to an owner's manual  for operating the National Security Council....This is a book Reagan's  people could have used and George Bush ought to read." —Bob Schieffer, The Washington Monthly
