Nuclear Issues

A interview conducted by The Fletcher School Forum with Ambassador Nicholas Burns, Former Under Secretary of State for Political Affairs.

Former U.S. Defense Secretary Ash Carter speaks with The WorldPost’s editor in chief, Nathan Gardels, about the Trump administration’s new China policy, North Korea and the pending U.S. withdrawal from the Intermediate-Range Nuclear Forces Treaty.

Would China escalate to nuclear use in a conventional war with the United States? If China believed that U.S. conventional attacks on missiles, submarines, air defenses, and command and control systems threatened the survivability of its nuclear forces or that the United States was preparing a counterforce attack, it might engage in limited nuclear escalation to gain military advantage or coerce the United States. The United States will face difficult trade-offs in deciding how best to manage the risk of nuclear escalation.

China's growing nuclear arsenal threatens to erode the United States' damage-limitation capability—its ability to destroy Chinese forces and thereby significantly reduce the damage that an all-out Chinese nuclear attack would inflict on the United States. Nevertheless, the United States should not attempt to preserve this capability. Doing so is technologically infeasible, would not add to the U.S. nuclear deterrent, would heighten tensions with China, and would increase the risk of nuclear escalation in a crisis.

Professor Meghan O'Sullivan was interviewed on November 15th, 2015 for a Wall Street Journal special section on energy, discussing the rapid transformation of the American energy sector in light of low fuel prices, new climate policies and other factors.

Many analysts worry that recent advances in U.S. military capabilities could cause China to abandon its nuclear strategy of assured retaliation and its no-first-use doctrine. The writings and statements of Chinese nuclear experts, however, suggest that such fears are misplaced.

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.

Iran’s top nuclear negotiator was heading back to Tehran on Sunday to consult with his nation’s leadership, as negotiators remained divided over how to limit and monitor Tehran’s nuclear program and even on how to interpret the preliminary agreement they reached two months ago.
