1. Is It a Nuke?: Pre-Launch Ambiguity and Inadvertent Escalation

Author:

Publication Date:

Content Type:
Special Report
Institution:
Carnegie Endowment for International Peace
Abstract:
Ambiguity about whether a weapon is nuclear-armed prior to its launch is an underappreciated, serious, and growing danger. Rising geopolitical tensions and the decay of arms control are exacerbating the risk that such pre-launch warhead ambiguity could lead to nuclear use in a crisis or conflict. Recent developments in technology—as well as potential future advances, such as the development of ambiguous intercontinental missiles—further add to the danger. A first step toward reducing these risks is to enhance awareness among decisionmakers of the causes and potential consequences of ambiguity. Unilateral and cooperative risk-mitigation measures could further reduce the danger of escalation, including in conflicts between the United States and Russia or the United States and China.

2. Silver Bullet? Asking the Right Questions About Conventional Prompt Global Strike

Author:
James M. Acton
Publication Date:

Content Type:
Working Paper
Institution:
Carnegie Endowment for International Peace
Abstract:
The development of non-nuclear weapons that can strike distant targets in a short period of time has been a U.S. goal for more than a decade. Advocates argue that such Conventional Prompt Global Strike (CPGS) weapons could be used to counter antisatellite weapons or sophisticated defensive capabilities; deny a new proliferator the ability to employ its nuclear arsenal; and kill high-value terrorists. Critics worry that CPGS weapons could create serious strategic risks, most notably of escalation—including to the nuclear level—in a conflict.

3. Beyond Treaties: Immediate Steps to Reduce Nuclear Dangers

Author:

Publication Date:

Content Type:
Policy Brief
Institution:
Carnegie Endowment for International Peace
Abstract:
The U.S. political parties are divided on nuclear weapons policy. Meanwhile, the United States and Russia have reached an arms control impasse and no new agreement is on the horizon. Confidence-building measures could help reduce nuclear risks between the United States and Russia, advancing the goals of both countries and both U.S. presidential candidates.

4. Why Fukushima Was Preventable

Author:

Publication Date:

Content Type:
Working Paper
Institution:
Carnegie Endowment for International Peace
Abstract:
Public sentiment in many states has turned against nuclear energy following the March 2011 accident at Japan's Fukushima Daiichi Nuclear Power Station. The large quantity of radioactive material released has caused significant human suffering and rendered large stretches of land uninhabitable. The cleanup operation will take decades and may cost hundreds of billions of dollars.

5. Japan Crisis Not As Bad As Chernobyl

Abstract:
As the crisis deepens at the Daiichi reactors in Fukushima, Japanese authorities are working to cool the reactors and limit the spread of radiation. The severity of the situation is both unclear and fluid, since measuring gauges at the Daiichi reactors are unreliable and radiation levels have fluctuated greatly on-site. Speaking on NBC's Today Show, Carnegie's James Acton describes the Fukushima reactor crisis as worse than Three Mile Island, though less disastrous than Chernobyl. During the Chernobyl catastrophe, Acton said, a significant fraction of the reactor core explosively spread into the environment. In Japan, the primary threat comes from the melting of the reactor core, exposing fuel rods to the atmosphere. The amount of radiation that will be released from such melting is unclear, Acton concluded.

6. Low Numbers: A Practical Path to Deep Nuclear Reductions

Author:
James M. Acton
Publication Date:

Content Type:
Working Paper
Institution:
Carnegie Endowment for International Peace
Abstract:
U.S. policy seeks to create the conditions that would allow for deep reductions in nuclear arsenals. This report offers a practical approach to reducing the U.S. and Russian stockpiles to 500 nuclear warheads each and those of other nuclear armed states to no more than about half that number. This target would require Washington and Moscow to reduce their arsenals by a factor of ten.
