Should America Promote Democracy Abroad?

This is about an hour of good discussion with Elliot Abrams and Nicholas Burns on how best to use American foreign policy as a tool for promoting democracy. They talk at length about the illusive balancing act between US interests (economic, geopolitical, etc) and the ideals of America (democracy, freedom, etc) in the process of conducting US foreign policy. They both agree on the need to balance between what is "just" and what is "practical," but they differ on how and when the US should use its hard/soft power to promote democracy and freedom.
