President Obama and Mitt Romney meet for their third debate to discuss foreign policy on Monday, when moderator Bob Schieffer is sure to ask them about last month's terrorist attack in Libya and the nuclear capabilities of Iran.

In anticipation of the final match between the presidential candidates, researchers from five centers at Stanford’s Freeman Spogli Institute for International Studies ask the additional questions they want answered and explain what voters should keep in mind.

What can we learn from the Arab Spring about how to balance our values and our interests when people in authoritarian regimes rise up to demand freedom?  

What to listen for: First, the candidates should address whether they believe the U.S. has a moral obligation to support other peoples’ aspirations for freedom and democracy. Second, they need to say how we should respond when longtime allies like Egypt’s Hosni Mubarak confront movements for democratic change.

And that leads to more specific questions pertaining to Arab states that the candidates need to answer: What price have we paid in terms of our moral standing in the region by tacitly accepting the savage repression by the monarchy in Bahrain of that country's movement for democracy and human rights?  How much would they risk in terms of our strategic relationship with Bahrain and Saudi Arabia by denouncing and seeking to restrain this repression? What human rights and humanitarian obligations do we have in the Syrian crisis?  And do we have a national interest in taking more concrete steps to assist the Syrian resistance?  On the other hand, how can we assist the resistance in a way that does not empower Islamist extremists or draw us into another regional war?  

Look for how the candidates will wrestle with difficult trade-offs, and whether either will rise above the partisan debate to recognize the enduring bipartisan commitment in the Congress to supporting democratic development abroad.  And watch for some sign of where they stand on the spectrum between “idealism” and “realism” in American foreign policy.  Will they see that pressing Arab states to move in the direction of democracy, and supporting other efforts around the world to build and sustain democracy, is positioning the United States on “the right side of history”?

What do you consider to be the greatest threats our country faces, and how would you address them in an environment of profound partisan divisions and tightly constrained budgets? 

What to listen for: History teaches that some of the most effective presidential administrations understand America's external challenges but also recognize the interdependence between America's place in the world and its domestic situation.

Accordingly, Americans should expect their president to be deeply knowledgeable about the United States and its larger global context, but also possessed of the vision and determination to build the country's domestic strength.

The president should understand the threats posed by nuclear proliferation and terrorist organizations. The president should be ready to lead in managing the complex risks Americans face from potential pandemics, global warming, possible cyber attacks on a vulnerable infrastructure, and failing states.

Just as important, the president needs to be capable of leading an often-polarized legislative process and effectively addressing fiscal challenges such as the looming sequestration of budgets for the Department of Defense and other key agencies. The president needs to recognize that America's place in the world is at risk when the vast bulk of middle class students are performing at levels comparable to students in Estonia, Latvia and Bulgaria, and needs to be capable of engaging American citizens fully in addressing these shared domestic and international challenges.

Should our government help American farmers cope with climate impacts on food production, and should this assistance be extended to other countries – particularly poor countries – whose food production is also threatened by climate variability and climate change?

What to listen for: Most representatives in Congress would like to eliminate government handouts, and many would also like to turn away from any discussion of climate change. Yet this year, U.S. taxpayers are set to pay up to $20 billion to farmers for crop insurance after extreme drought and heat conditions damaged yields in the Midwest.

With the 2012 farm bill stalled in Congress, the candidates need to be clear about whether they support government subsidized crop insurance for American farmers. They should also articulate their views on climate threats to food production in the U.S. and abroad.

Without a substantial crop insurance program, American farmers will face serious risks of income losses and loan defaults. And without foreign assistance for climate adaptation, the number of people going hungry could well exceed 15 percent of the world's population.

What is your vision for the United States’ future relationship with Europe? 

What to listen for: Between the end of World War II and the end of the Cold War, it was the United States and Europe that ensured world peace. But in recent years, it seems that “Europe” and “European” have become pejoratives in American political discourse. There’s been an uneasiness over whether we’re still friends and whether we still need each other. But of course we do.

Europe and the European Union share with the United States of America the most fundamental values, such as individual freedom, freedom of speech, freedom to live and work where you choose. There’s a shared respect of basic human rights. There are big differences with the Chinese, and big differences with the Russians. When you look around, it’s really the U.S. and Europe together with robust democracies such as Canada and Australia that have the strongest sense of shared values.

So the candidates should talk about what they would do as president to make sure those values are preserved and protected and how they would make the cooperation between the U.S. and Europe more effective and substantive as the world is confronting so many challenges like international terrorism, cyber security threats, human rights abuses, underdevelopment and bad governance.

Historical and territorial issues are bedeviling relations in East Asia, particularly among Japan, China, South Korea, and Southeast Asian countries. What should the United States do to try to reduce tensions and resolve these issues?

What to listen for: Far from easing as time passes, unresolved historical, territorial, and maritime issues in East Asia have worsened over the past few years. There have been naval clashes, major demonstrations, assaults on individuals, economic boycotts, and harsh diplomatic exchanges. If the present trend continues, military clashes – possibly involving American allies – are possible.

All of the issues are rooted in history. Many stem from Imperial Japan’s aggression a century ago, and some derive from China’s more assertive behavior toward its neighbors as it continues its dramatic economic and military growth. But almost all of problems are related in some way or another to decisions that the United States took—or did not take—in its leadership of the postwar settlement with Japan.

The United States’ response to the worsening situation so far has been to declare a strategic “rebalancing” toward East Asia, aimed largely at maintaining its military presence in the region during a time of increasing fiscal constraint at home. Meanwhile, the historic roots of the controversies go unaddressed.

The United States should no longer assume that the regional tensions will ease by themselves and rely on its military presence to manage the situation. It should conduct a major policy review, aimed at using its influence creatively and to the maximum to resolve the historical issues that threaten peace in the present day.

Former U.S. Ambassador to Afghanistan Karl Eikenberry has been awarded a William J. Perry Fellowship in International Security at Stanford’s Center for International Security and Cooperation (CISAC), where he will continue to address emerging security challenges facing the United States.

Ambassador Eikenberry has an ambitious agenda for the coming academic year, which includes teaching and mentoring students, public speaking and working closely with former Secretary of Defense William Perry. He also will take part in activities at the Walter H. Shorenstein Asia-Pacific Research Center (APARC), such as the new China and the World research initiative.

“It’s a lifetime honor to receive the Perry Fellowship,” says Eikenberry. “I can’t think of an American in modern times who has better exemplified inspirational commitment to public service than Dr. William Perry. And I can’t think of a better institute of higher learning to be associated with than Stanford University.”

Ambassador Eikenberry has been at Stanford since September 2011 as the Frank E. and Arthur W. Payne Distinguished Lecturer and is an affiliated faculty member for CISAC, APARC and the Center on Democracy, Development and the Rule of Law (CDDRL), as well as research affiliate at the Europe Center – all policy research centers within Stanford’s Freeman Spogli Institute of International Studies.

Before coming to Stanford, Ambassador Eikenberry led the civilian surge directed by President Obama from 2009 to 2011 in an effort to reverse the momentum gained by insurgents, and set the conditions for a transition to Afghanistan sovereignty. He retired from his 35-year military career in April 2009 with the rank of U.S. Army Lieutenant General after posts including commander and staff officer with mechanized, light, airborne and ranger infantry units in the United States, as well as Korea, Italy and as the Commander of the American-led Coalition Forces from 2005-2007.

"Karl Eikenberry's record of public service amply demonstrates his unique qualities, not only as a leader of the American military at a challenging time, but as a strategic thinker and an insightful diplomat,” says CISAC Co-Director Mariano-Florentino Cuéllar. “He has a rare understanding of the profound challenges facing our world, and has been a tremendous asset to CISAC and Stanford.”

Ambassador Eikenberry’s research areas include U.S. strategy in the Asia-Pacific region; China’s evolving security strategy; the United States and NATO; the future of the U.S. military; Washington’s policies in Central and South Asia; and assessing the risks of military intervention.

The fellowship was established to honor Perry, the 19^th U.S. secretary of defense and former CISAC co-director, and to recognize his leadership in the cause of peace. Perry is co-director of the Preventive Defense Project and the Nuclear Risk Reduction Initiative at CISAC and is an expert on U.S. foreign policy, national security and arms control. Perry Fellows spend a year at CISAC conducting policy-relevant research on international security issues. They join other distinguished scientists, social and political scientists and engineers who work together on problems that cannot be solved within a single field of study.

Ambassador Eikenberry is a graduate of the U.S. Military Academy, has master’s degrees from Harvard University in East Asian Studies and Stanford University in Political Science, and was a National Security Fellow at the Kennedy School of Government at Harvard. He earned an Interpreter’s Certificate in Mandarin Chinese from the British Foreign Commonwealth Office while studying at the United Kingdom Ministry of Defense Chinese Language School in Hong Kong, and has an Advanced Degree in Chinese History from Nanjing University in the People’s Republic of China.
