Nuclear Issues

This article presents both the fundamental changes that have taken place in Israel's strategic environment, from conventional, state-based threats to primarily asymmetrical ones, and the responses it has developed to date. It also addresses Israel's relations with the United States and other primary international actors, as well as Israel's nuclear and regional arms control policy.

The author analyzes the policy implications of the U.S. January 2019 Missile Defense Review.

The paper provides a detailed analysis of the contemporary Sino-Indian conventional ground and nuclear force balances and carefully reconstructs how mutual developments in these areas are perceived by both New Delhi and Beijing.

Belfer Center Director and former Secretary of Defense Ash Carter talks about pulling out of the Iran Deal, North Korea, and more on CNN New Day with Chris Cuomo.

An escalating arms race between Russia and the U.S. is bad news for international security. But apart from Russia's recent withdrawal from the INF treaty, Simon Saradzhayn argues, Vladimir Putin's fixation on missile defense should also be cause for concern.

"Just as U.S. nuclear strategy and arsenal expansions affect those of China, China's nuclear shifts affect India's threat perceptions. Pakistan, in turn, pays close attention to any growth in Indian nuclear forces. To avoid a nuclear chain reaction in Asia, Congress should take a stand against proliferation and refuse to fund these new weapons programs."

The escalating threats between North Korea and the United States make it easy to forget the “nuclear nightmare,” as former US Secretary of Defense William J. Perry put it, that could result even from the use of just a single terrorist nuclear bomb in the heart of a major city.

At the risk of repeating the vast literature on the tragedies of Hiroshima and Nagasaki—and the substantial literature surrounding nuclear tests and simulations since then—we attempt to spell out here the likely consequences of the explosion of a single terrorist nuclear bomb on a major city, and its subsequent ripple effects on the rest of the planet. Depending on where and when it was detonated, the blast, fire, initial radiation, and long-term radioactive fallout from such a bomb could leave the heart of a major city a smoldering radioactive ruin, killing tens or hundreds of thousands of people and wounding hundreds of thousands more. Vast areas would have to be evacuated and might be uninhabitable for years. Economic, political, and social aftershocks would ripple throughout the world. A single terrorist nuclear bomb would change history. The country attacked—and the world—would never be the same.
