U.S. Foreign Policy: Back to the Water's Edge is based on the old idea that despite domestic differences and party politics, Americans should unite "at the water's edge" and present a cohesive front to a hostile world. The fifth edition explores this theme through coverage of the Trump administration, its early policies, and how Trump's initiatives fit into the broader historical patterns of foreign policy in the United States. More compact than most of its competitors, the fifth edition packs necessary information and concepts into a lean but readable format. It contains rich historical content, providing the reader with snapshots of some of the truly classic highlights-and lowlights-of America's record in foreign affairs. Written with the student reader in mind, each chapter offers several pedagogical aids designed to reinforce and extend comprehension of the material. This text is also accompanied by a companion reader. Regional Cases in Foreign Policy, Second Edition, was written by Don Snow with the specific intention of providing material and perspectives not contained in the text. The reader contains fourteen mini-cases that can accompany classroom discussions or lectures on subjects as diverse as relations with Russia, Israel, or the Islamic State; specific questions like the border fence with Mexico; U.S.-Cuban relations; or the British withdrawal from the European Union (Brexit). Case examples are drawn from all parts of the world.

During his first term in office, Pres. George W. Bush made reference to the "unitary executive" ninety-five times, as part of signing statements, proclamations, and executive orders. Pres. Barack Obama's actions continue to make issues of executive power as timely as ever.
Unitary executive theory stems from interpretation of the constitutional assertion that the president is vested with the "executive power" of the United States. In this groundbreaking collection of studies, eleven presidential scholars examine for the first time the origins, development, use, and future of this theory.
"
The Unitary Executive and the Modern Presidency" examines how the unitary executive theory became a recognized constitutional theory of presidential authority, how it has evolved, how it has been employed by presidents of both parties, and how its use has affected and been affected by U.S. politics. This book also examines the constitutional, political, and even psychological impact of the last thirty years of turmoil in the executive branch and the ways that controversy has altered both the exercise and the public's view of presidential power.
