Nuclear Issues

The risks of nuclear escalation between the U.S. and China or Russia are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. What can be done to reduce this risk?

The historical record does not support the idea that nuclear energy programs increase the odds of proliferation.

Olli Heinonen Briefing at the Open Debate of the United Nations Security Council in New York, NY on February 13, 2017.

William H. Tobey reviews the motivations, strengths, and weaknesses of the nuclear security summits and provides recommendations for how governments can maintain momentum and awareness now that the summit process is over. He concludes that some of the innovations from the process will continue to be useful tools.

This policy brief is based on "Should the United States Reject MAD? Damage Limitation and U.S. Nuclear Strategy toward China" which will appear in the summer 2016 issue of International Security.

Aaron Arnold, Associate of the Project on Managing the Atom at the Belfer Center, writes in The Diplomat that a key threat to the ongoing implementation of the Iran nuclear deal is the risky nature of the Iranian financial sector. While Iran is banking on receiving greater foreign investment, continued problems with the Iranian financial sector, including lack of sufficient regulatory controls and the potential ties to terrorist financing, have made companies cautious about investing in Iran. He suggests that the United States work with Iran to bring its banking system up to the same standard as the global economy, and to consider closer integration of Iran into the world economy in order to preserve the effects of the nuclear agreement.

Senior Fellow William Tobey testified on March 17, 2016, before the Senate Foreign Relations Committee on "Reviewing the Administration’s Nuclear Agenda."

The Iran nuclear deal was officially implemented on Saturday, as Iran successfully fulfilled its initial key nuclear commitments and the international community relieved major sanctions, including unfreezing about $100 billion of Iranian money. Implementation Day was met with applause from deal supporters in the U.S. and Iran, while critics have raised questions about whether Iran will adhere to its requirements and how it will flex its newfound economic power. Also in recent days, the U.S. and Iran agreed to a prisoner swap that led to the freedom of Washington Post reporter Jason Rezaian and others, and negotiated the release of American sailors detained in Iran. What does the arrival of Implementation Day mean for Iran’s nuclear program and nuclear nonproliferation, and how does it bode for the future of U.S.-Iran relations? We asked Belfer Center experts to weigh in on these and related questions.

China's continuing commitment to a nuclear strategy of assured retaliation indicates that it will prioritize avoiding a nuclear arms race with the United States. Nevertheless, leaders and militaries in both countries will need to be exceptionally careful to avoid nuclear escalation in a crisis.

Aaron Arnold, Associate with the Project on Managing the Atom at the Belfer Center, writes in The Hill that while Iran will soon be getting sanctions relief as the nuclear accord with the P5+1 is enacted, it has not yet taken steps to update its banking system and bring it up to international money laundering and counter-terror financing. He also suggests that in order to balance the competing political and financial concerns at play with sanctions, the international community led by the United States should make clear conditions for both exclusion and rejoining of the international financial system.
