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.

Nuclear weapons remain the most powerful weapons on the planet and how President Donald Trump’s team manages nuclear issues is critical to our security. These are hard challenges; none were perfectly addressed under President Obama’s leadership. But we made them a priority from day one. Whether or not the new team puts them at the top of the to-do list, here are five issues that will demand their attention before too long.

The Project on Managing the Atom offers fellowships for pre-doctoral, post-doctoral, and mid-career researchers for one year, with a possibility for renewal, in the stimulating environment of the Belfer Center for Science and International Affairs at the Harvard Kennedy School. The online application for 2016-2017 fellowships opened December 15, 2015, and the application deadline is January 15, 2016. Recommendation letters are due by February 1, 2016.

Many accounts suggest that the United States did little to prevent Israel, Pakistan, and South Africa from developing nuclear weapons. These accounts are flawed, however. The United States did attempt to stop all three countries from acquiring the bomb and, when those efforts failed, to halt additional proliferation measures such as further testing and weaponization.

The ninth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) will be held at the UN Headquarters in New York from April 27-May 22, 2015. This is the fourth such conference since the indefinite extension of the NPT in 1995. Participating governments will discuss nuclear disarmament, non-proliferation, and the peaceful use of nuclear energy with a view to arriving at consensus on a number of issues.

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.

The death from natural causes of an old man in North Korea this month should have been the closing chapter of the tale of Pakistan's nuclear and missile cooperation with the Hermit Kingdom. Instead, it may mark the next episode in the saga of Iran's controversial nuclear program.

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.

As the growth of nuclear industry during the coming decade is considered to increase, the number of cylinder shipments will expand accordingly. Beyond that, new vendors with less experience will enter the uranium conversion and enrichment market. Under such a scenario, there is no reason to discount the disappearance of interest to nuclear proliferation or illicit trafficking of nuclear material. Thus an enhanced system to track UF6 movements is a must. Better to be safe than sorry.
