Professor Peter Hahn has published seven books on the history of American diplomacy in the Middle East, most recently Missions Accomplished? The United States and Iraq since World War I (Oxford University Press), as well as scores of articles, essays, and reviews.  As an accomplished research scholar he has two additional books forthcoming in 2025: a second edition of his best selling textbook, Crisis and Crossfire: The United States and the Middle East since 1945 (Potomac Books), as well as Libya and the West: What Everyone Needs to Know (Oxford University Press). Professor Hahn has conducted research in the archives of the United States, Israel, Britain, and France; delivered scholarly papers and invited lectures in eleven countries; consulted with policymakers in the U.S. Departments of State, Defense, and Justice and with senior officers of the Ohio National Guard; and given interviews to the media on six continents. 

Crisis and Crossfire traces the origins of the contemporary challenges facing the United States in the Middle East by analyzing the broad contours of U.S. policy in the region since the government’s first involvement there in the 1940s.  Hahn evaluates U.S. policy in the context of such global phenomena as the Cold War and the multipolar international order that emerged in the early 2000s. He explains how the United States has tried, with varying degrees of success, to curtail, modify, and channel Arab and Iranian nationalist movements to serve U.S. interests. Crisis and Crossfire examines the U.S. approach to the Arab-Israeli conflict through eight decades, exploring the interstate wars of the 1940s–1980s, the quests to make peace in the 1970s–2010s, and the enduring strife between Israel and Palestine. Hahn details how the United States has assumed growing responsibility for regional stability and security in the Middle East since World War II, culminating in involvement in the Gulf War to liberate Kuwait and the invasions and occupations of Afghanistan and Iraq. This second edition provides a balanced  explanation of the Israeli-Palestinian Gaza War; the U.S. stand-off with Iran; the proxy wars in Lebanon, Yemen, Libya, and Syria; the threat of terrorism; and related topics.
