Making a Difference

A front-row memoir of power, war, diplomacy, and dissent from one of the most influential national security insiders of the twentieth century. From the Pentagon Papers to the Nixon White House, from Vietnam and nuclear arms negotiations to civil liberties battles at the ACLU and diplomacy in the Clinton administration, Morton H. Halperin has spent more than half a century at the center of America’s most consequential political and foreign policy struggles. In this sweeping memoir, Halperin pulls readers inside the rooms where history was made—working alongside figures like Robert McNamara, Henry Kissinger, Clark Clifford, and Lyndon Johnson during the height of the Cold War. A brilliant young Harvard scholar who entered government expecting to stay only briefly, Halperin instead became a key architect, critic, and witness to some of the defining crises of modern American power. With remarkable candor and intellectual rigor, Halperin recounts the internal battles over Vietnam strategy, secret bombing campaigns, nuclear arms control, the Pentagon Papers, government surveillance, civil liberties, and the evolving role of American democracy on the world stage. Along the way, he reveals how policy is truly made—not through grand theories alone, but through bureaucracy, personality, moral compromise, and relentless institutional conflict. This insider chronicle of Washington at its most turbulent is the story of a man who moved from idealistic academic to influential policymaker while never abandoning his commitment to democratic accountability and constitutional freedom. It is essential reading for anyone seeking to understand how American foreign policy really works—and what it costs the people who shape it.
