Since 2003, India has been building its nuclear arsenal beyond what is necessary for a purely retaliatory or minimum deterrence capability. India’s actions could lead to a regional arms race or even the use of nuclear weapons in a war with Pakistan.

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

Contrary to conventional wisdom, states with nuclear energy programs are not more likely than those without them to seek or acquire nuclear weapons.

Understanding which nuclear proliferation strategies are available to states and how to thwart them is crucial for global security. Analysis of the strategies chosen by potential proliferators, and particularly the history of India’s nuclear program, shows how states choose among four possible proliferation strategies: hedging, sprinting, hiding, and sheltered pursuit. Each strategy has vulnerabilities that can be exploited to prevent proliferation.

This article reviews the motivations, strengths, and weaknesses of the Nuclear SecuritySummits (NSS), both procedurally and substantively.

The 2016 nuclear security summit was a pivotal moment for the decades-long effort to secure nuclear material around the globe. More than 50 national leaders gathered in Washington for the last of four biennial meetings that have led to significant progress in strengthening measures to reduce the risk of nuclear theft.

Indian Prime Minister Narendra Modi traveled to Washington last week, making his fourth trip to the United States since taking office just two years ago. India and South Asia Program Fellow, Ronak Desai examines the strategic approach to India's relations with the United States.

The United Nations’ nuclear watchdog has certified Tehran’s compliance with the terms of a nuclear accord the United States, Iran and other world powers reached in April 2015. The historic agreement is aimed at curtailing Iran’s controversial nuclear program, and paves the way for longstanding sanctions against Tehran to be lifted. Sanctions targeting Iran, and particularly its lucrative energy sector, have crippled the country economically and isolated it diplomatically.

Ronak Desai examines what the lifting of Iran sanctions mean for India.
