Threats to American unity are not unique to modern times. In the 1960s, the assassination of President Kennedy, the tension of racial strife, the political extremes of the Radical Right with its John Birchers and the Radical Left with its threat of Communism all raised critically urgent questions relative to our national unity, to our political stability, and to our vaunted respect for the rule of law. The Challenges to Democracy is an assessment of the foundations of political unity in the United States.

The American consensus, as Murray Clark Havens defines it, emphasizes a set of values and procedures that most Americans, since the adoption of the Constitution, have accepted in principle: religious tolerance, individual freedom in intellectual and cultural matters, the importance of education and intellectual effort, settlement of internal conflict through peaceful and political processes, the supremacy of law, a high and generally rising standard of living, and, since the Civil War, racial compatibility.

Never in our history have the ideals of this consensus been fully achieved, but as long as the majority of our citizens accept the validity of those ideals and the democratic procedures for realizing them, the basic American political unity is not threatened. However, when citizens who cannot accept the elements of the American consensus become influential enough to block the democratic process, then that consensus is threatened.

Havens shows how such threats have come to us all through our history—the Civil War, racial and religious bigotry, the Ku Klux Klan, Huey Long, Father Coughlin and other extremists of the desperate thirties, McCarthyism. He discusses contemporary dangers to American unity such as those connected with the acceptance of the African American, religious friction in politics and government, the Radical Right and the Radical Left, and our foreign policy as an expression of the American consensus.

The broad conclusions of this study are that our national unity is continuously in jeopardy, with frequent recurrences of serious questions as to the permanence of some of the patterns we have always associated with American government, but that our democracy is possessed of considerable potential for survival because of our deep national commitment to democracy and because of our even deeper nationalism.

Why do people join violent extremist movements? What attracts so many to fight for terrorist groups like al-Shabab, al-Qaida, and the Islamic State? Journalism professor Joseph Weber answers these questions by examining the case of the more than fifty Somali Americans, mostly young men from Minnesota, who made their way to Somalia or Syria, attempted to get to those countries, aided people who did, or financially backed terrorist groups there. Often defying parents who had fled to the United States seeking safety and prosperity for their children, many of these youths ended up dead, missing, or imprisoned. But for every person who went on or attempted this journey believing they were rising to the defense of Islam, more rejected the temptations of terrorism. What made the difference? The book takes a close look at one man from Minneapolis, the American-born son of a couple who had fled Somalia, who came dangerously close to answering the ISIS call. Abdirahman Abdirashid Bashir’s cousins and friends had taken up arms for the group and reached out to him to join them. From 2014 to 2016 he and a dozen friends—some still in their teens—schemed to find ways to get to Syria. Some succeeded. In the end, Bashir made a different choice. Not only did he reject ISIS’s call, he decided to work with the FBI to spy on his friends and ultimately to testify against them in court. Drawing on extensive interviews, Weber explains why.

What is driving political extremism in Pakistan? In early 2011, the prominent Pakistani politician Salmaan Taseer was assassinated by a member of his own security team for insulting Islam by expressing views in support of the rights of women and religious minorities. Benazir Bhutto, the former prime minister, was killed by gunfire and explosive devices as she left a campaign event in December 2007; strong evidence links members of extremist organizations to her slaying.

These murders underscore the fact that religion, politics, and policy are inextricably linked in Pakistan. In this book, Haroon K. Ullah analyzes the origins, ideologies, bases of support, and electoral successes of the largest and most influential Islamic parties in Pakistan. Based on his extensive field work in Pakistan, he develops a new typology for understanding and comparing the discourses put forth by these parties in order to assess what drives them and what separates the moderate from the extreme. A better understanding of the range of parties is critical for knowing how the US and other Western nations can engage states where Islamic political parties hold both political and moral authority.

Pakistan’s current democratic transition will hinge on how well Islamic parties contribute to civilian rule, shun violence, and mobilize support for political reform. Ullah’s political-party typology may also shed light on the politics of other majority-Muslim democracies, such as Egypt and Tunisia, where Islamist political parties have recently won elections.
