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.

During the 1971 Bangladesh war for independence from Pakistan, the Pakistan army carried out a genocide that killed hundreds of thousands of Bengalis in what was then East Pakistan. The perpetrators never faced trial. Archival documents reveal how India and Bangladesh sacrificed the opportunity for war crimes trials to gain Pakistan’s agreement on key security goals—the Simla peace agreement and recognition of Bangladesh’s independence. The legacy of this decision continues to blight Bangladesh’s politics.

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.

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.

When do states acquire nuclear weapons? History shows that only two types of states decide that the bomb is essential to their security: 1) very powerful states; and 2) weak states that lack ironclad security guarantees.

Critics of ethnofederalism—a political system in which federal subunits reflect ethnic groups’ territorial distribution—argue that it facilitates secession and state collapse. An examination of post-1945 ethnofederal states, however, shows that ethnofederalism has succeeded more often than not.

Policymakers have long focused on preventing nuclear weapons proliferation by controlling technology. Even developing countries, however, may now possess the technical ability to create nuclear weapons. The history of gas centrifuge development in twenty countries supports this perspective. To reduce the demand for nuclear weapons, policymakers will have look toward the cultural, normative, and political organization of the world.

Why has transnational war volunteering increased so dramatically in the Muslim world since 1980? Standard explanations, which emphasize U.S.-Saudi support for the 1980s Afghan mujahideen, the growth of Islamism, or the spread of Wahhabism are insufficient. The increase in transnational war volunteering is better explained as the product of a pan-Islamic identity movement that grew strong in the 1970s Arab world from elite competition among exiled Islamists in international Islamic organizations and Muslim regimes.

"The United States' determination on minimizing Iran's regional role has led in actuality to the adoption and pursuit of an oppositional posture and role on the part of Iran. This dichotomous situation and role-playing has important implications for foreign policymakers in Tehran and Washington. If the United States continues to ignore Iran's increased role in the region, Washington risks disrupting the natural power equations, potentially exacerbating the conflict. If, however, the United States can accept Iran's role in the region's new security architecture, especially in the Persian Gulf area, and change its policy of castigating Iran as the main source of threat for the region, Washington and Tehran can ultimately reach a practical rapprochement and find an accommodation that will advance the interests of both states in the region."
