Nuclear Issues

From sharply rising tensions with a nuclear North Korea and decertification of the Iran nuclear deal to China’s growing global assertiveness and the State Department pullback from projecting American values, such as democracy and human rights, around the world, the United States faces urgent national security challenges.

In a panel discussion Monday evening at Harvard Kennedy School (HKS) moderated by MSNBC host Rachel Maddow, former members of President Obama’s cabinet described what they see as a fraying of alliances, a loss of credibility with allies and enemies, a stepping back as a leader on human rights and democracy, and a relinquishment of diplomacy as a critical component of national security.

The defining question about global order for this generation is whether China and the United States can escape Thucydides’s Trap. The Greek historian’s metaphor reminds us of the attendant dangers when a rising power rivals a ruling power—as Athens challenged Sparta in ancient Greece, or as Germany did Britain a century ago. Most such contests have ended badly, often for both nations, a team of mine at the Harvard Belfer Center for Science and International Affairs has concluded after analyzing the historical record. In 12 of 16 cases over the past 500 years, the result was war. When the parties avoided war, it required huge, painful adjustments in attitudes and actions on the part not just of the challenger but also the challenged.

In 1985, researchers at the Harvard Kennedy School published a book called “Hawks, Doves, and Owls,” and gave it an ambitious subtitle: “An Agenda for Avoiding Nuclear War.” Those scholars gathered again at the School on Monday (May 16) for a seminar on the current challenges in avoiding nuclear war — and to marvel at just how drastically the nuclear threat has morphed in the two decades since the Cold War ended and the Soviet Union collapsed.
