Paul D. Miller offers a tough minded critique of recent trends in American grand strategy. He rejects retrenchment but also the excesses of liberal internationalism. He prescribes a conservative internationalist grand strategy to preserve the American security and leadership in the world while avoiding overstretch. Originally written before the 2016 US presidential election, this first paperback edition contains a new preface that repositions the book’s argument for the Trump era. Miller explains why President Trump’s nationalist vision for American grand strategy damages US interests and world order. Miller blends academic rigor with his experiences as former member of the National Security Council and intelligence community to offer prescriptions for US grand strategy. He advocates for narrowing regional priorities and focusing on five strategic objectives: balancing against the nuclear autocracies, championing liberalism to maintain a favorable balance of power, thwarting the transnational jihadist movement, investing in governance in weak and failed states, and strengthening homeland security. This book is a must read for scholars and students of international affairs and for anyone who is concerned about America’s role in the world.
