In 1978, the Polish cardinal Karol Wojtyla was elected to the papacy of the Catholic Church, taking the name John Paul II. In the twenty-four years since, Pope John Paul II has traveled more widely and held audiences for more people than any other pope in history. But beyond his long service and high profile, how will John Paul II be remembered? Will he be remembered more for his political impact—many say that he played a crucial role in the fall of communism in Eastern Europe—or for his ecclesiastical work? Just how well has John Paul II prepared the Catholic Church for the twenty-first century?

It has been more than fifteen years since the People's Liberation Army crushed the prodemocracy rallies in Tiananmen Square in Beijing, killing hundreds of students and workers and wounding thousands more. Since then, although stifling political dissent, China has continued to liberalize its economy and is rapidly becoming an economic superpower. Will the explosion of new wealth in China lead to new pressures for democratic reform? And just what is the legacy of Tiananmen? Peter Robinson speaks with William McGurn and Orville Schell.

Fifty years ago, critic Lionel Trilling declared that "in the United States at this time, liberalism is not only the dominant but even the sole intellectual tradition." Today, however, even most Democrats avoid calling themselves liberal. What happened to the liberal tradition in the second half of the twentieth century? What does liberalism stand for at the beginning of the twenty-first century? Can liberals reclaim their once-dominant position in American politics, or is their ideology history?

On December 12, 2000, the Supreme Court of the United States brought an end to thirty-six days of dramatic vote recounts and legal challenges in the state of Florida. The decision let stand the initial results of Florida's election, which gave the state's electoral votes, and thus the Presidency, to George W. Bush. What was the legal justification for the Supreme Court's decision? Should the Court have intervened in the first place? And what precedent did the Court create for future elections?

The Crusades happened almost a thousand years ago—why do they still provoke an argument? Osama bin Laden has used them to attempt to rally the Islamic world to his cause; President Bush has called the war on terrorism a "crusade." But what is the truth about the Crusades? Were they motivated by savage greed and intolerance or by pious idealism? Were they an unprovoked attack by the West on the Islamic world or a reaction to centuries of Islamic incursions? How should we understand the legacy of the Crusades today, in a time of conflict between the West and radical Islamic terrorists?

George W. Bush, during the 2000 presidential campaign said that "America has never been an empire... We may be the only great power in history that had the chance, and refused." Was then-candidate Bush right when he made those remarks? Or has America become an imperial power in all but name? How do America's unique historical circumstances predispose it to handle the unrivaled power it holds in the world today? And what lessons can we draw from our nearest historical antecedent, the British Empire of the nineteenth and early twentieth centuries?

Since the end of the cold war, the United States has been the world's only superpower, accounting for 43 percent of the world's military expenditures. During this time, America has led major interventions into Kosovo, Afghanistan, and Iraq. Are the United States and the world better off when America follows a unilateral, interventionist foreign policy? Or should the United States reduce its overseas presence and instead emphasize international cooperation? Peter Robinson speaks with Niall Ferguson and Ivan Eland.

In 1960, John F. Kennedy ran to the right of Richard Nixon, arguing that under Republicans, the United States had become too weak in the cold war. A dozen years later, the Democratic presidential candidate was George McGovern. How did the Democratics go from hawks to doves in just twelve years? And what does the history of the Left imply for John Kerry, the Democratic Party, and the war on terror today? Peter Robinson speaks with Anne Applebaum and Christopher Hitchens.
