Allied nations often stop each other from going to war. Some countries even form alliances with the specific intent of restraining another power and thereby preventing war. Furthermore, restraint often becomes an issue in existing alliances as one ally wants to start a war, launch a military intervention, or pursue some other risky military policy while the other ally balks. In Warring Friends, Jeremy Pressman draws on and critiques realist, normative, and institutionalist understandings of how alliance decisions are made. Alliance restraint often has a role to play both in the genesis of alliances and in their continuation. As this book demonstrates, an external power can apply the brakes to an incipient conflict, and even unheeded advice can aid in clarifying national goals. The power differentials between allies in these partnerships are influenced by leadership unity, deception, policy substitutes, and national security priorities. Recent controversy over the complicated relationship between the U.S. and Israeli governments—especially in regard to military and security concerns—is a reminder that the alliance has never been easy or straightforward. Pressman highlights multiple episodes during which the United States attempted to restrain Israel's military policies: Israeli nuclear proliferation during the Kennedy Administration; the 1967 Arab-Israeli War; preventing an Israeli preemptive attack in 1973; a small Israeli operation in Lebanon in 1977; the Israeli invasion of Lebanon in 1982; and Israeli action during the Gulf War of 1991. As Pressman shows, U.S. initiatives were successful only in 1973, 1977, and 1991, and tensions have flared up again recently as a result of Israeli arms sales to China. Pressman also illuminates aspects of the Anglo-American special relationship as revealed in several cases: British nonintervention in Iran in 1951; U.S. nonintervention in Indochina in 1954; U.S. commitments to Taiwan that Britain opposed, 1954-1955; and British intervention and then withdrawal during the Suez War of 1956. These historical examples go far to explain the context within which the Blair administration failed to prevent the U.S. government from pursuing war in Iraq at a time of unprecedented American power.

Since its founding, the United States has allied with unsavory dictatorships to thwart even more urgent security threats. How well has the United States managed such alliances, and what have been their consequences for its national security? In this book, Evan N. Resnick examines the negotiating tables between the United States and its allies of convenience since World War II and sets forth a novel theory of alliance bargaining. Resnick’s neoclassical realist theory explains why U.S. leaders negotiate less effectively with unfriendly autocratic states than with friendly liberal ones. Since policy makers struggle to mobilize domestic support for controversial alliances, they seek to cast those allies in the most benign possible light. Yet this strategy has the perverse result of weakening leverage in intra-alliance disputes. Resnick tests his theory on America’s Cold War era alliances with China, Pakistan, and Iraq. In all three cases, otherwise hardline presidents bargained anemically on such pivotal issues as China’s sales of ballistic missiles, Pakistan’s development of nuclear weapons, and Iraq’s sponsorship of international terrorism. In contrast, U.S. leaders are more inclined to bargain aggressively with democratic allies who do not provoke domestic opposition, as occurred with the United Kingdom during the Korean War. An innovative work on a crucial and timely international relations topic, Allies of Convenience explains why the United States has mismanaged these “deals with the devil”—with deadly consequences.
