The global AIDS pandemic is now in its third decade. Although treatments have improved and infection rates have slowed in the West, AIDS continues to take a staggering toll in Africa. And experts believe that Eurasia, particularly Russia, China, and India, may be next. Is the United States doing enough to combat the global AIDS crisis? Should the United States continue its current policy, which includes an emphasis on getting antiretroviral drugs to millions who can't now afford them? Or does the United States need to focus more on pressuring affected countries to reform their inadequate social and economic institutions? Peter Robinson speaks with Carol Adelman and Greg Behrman.

Before September 11, we took it for granted that only nations or states could wage war on the United States. After 9/11 it became obvious that war could also be waged by terrorists operating anonymously and in the shadows. Are the laws of war—the Geneva Conventions, the International Convention on Torture—suited to this new reality of war? Whom may we detain? How may we interrogate those we detain? In the war on terror, do the laws of war permit us to be as tough as we need to be? Peter Robinson speaks with Peter Berkowitz and Jenny Martinez.

On July 1, the Coalition Provisional Authority—the body headed by U.S. ambassador Paul Bremer that has governed Iraq since the end of the Iraq war—will transfer sovereignty to a temporary Iraqi government.

Just what are our responsibilities in ensuring that success? And how long will or should the United States maintain a military presence in Iraq?

The moment is approaching when negotiations with the Palestinians will be less a reward for terrorism than a way for Israel to consolidate political gains.
