Is America going to play a dominant role in international affairs or is the U.S. in decline?
Is military power still the key to world leadership or has economic power become more important?
How can war be averted in the post-Cold War era?
Twice in the 20th century, the great powers engaged in wars that killed nearly 70 million people. During the past 50 years, the cold war has dominated our lives and international politics.
The series examines how concepts like the balance of power and the international system interweave with history. It asks what actually happened in these great conflicts, so we can better evaluate if we are destined to repeat them.
