How to Keep Nuclear Power Plants Operating Safely During the Coronavirus Pandemic

As the COVID-19 pandemic devastates the world, nuclear power plants must remain safe and secure to provide electricity for food supply chains, emergency response teams, hospitals, and telecommunications in countries home to more than half of all people. Meanwhile, the Islamic State terror group has already announced its intent to exploit the pandemic, and other violent extremist organizations are also taking pains to use the crisis for their own purposes.

Can Cyberwarfare Be Regulated?

| Oct. 02, 2019

Joseph Nye writes that In the cyber realm, the same program can be used for legitimate or malicious purposes, depending on the user’s intent. But if that makes traditional arms-control treaties impossible to verify, it may still be possible to set limits on certain types of civilian targets and negotiate rough rules of the road that limit conflict.

A newly drafted United States nuclear strategy that has been sent to President Trump for approval would permit the use of nuclear weapons to respond to a wide range of devastating but non-nuclear attacks on American infrastructure, including what current and former government officials described as the most crippling kind of cyberattacks.

New Ways to Detect Nuclear Misbehavior

| Jan. 08, 2018

If we had the technology to detect nuclear materials remotely it could help deter smuggling and make it easier to monitor international nuclear agreements. Several recent breakthroughs, if followed up with continued research and funding, could deliver on this promise. They include technological advances in x-ray and neutron radiography; a method that measures how plasma breaks down when exposed to a radioactive source; and developments in antineutrino detection. While all require more development and testing, they are important steps as the global need for ways to detect nuclear materials grows.

Iran and the US elections: Observations from a trip to Iran

| Dec. 13, 2016

Iran has entered uncharted territory following the landmark nuclear deal between Tehran and six world powers. I recently came back from a six-week trip to Iran where I had the opportunity to observe first-hand the changes, developments, and uncertainty in the country. The widespread optimism that initially surrounded the deal, and the expectations that it would bring an economic windfall, have been significantly diminished since, and there were many questions: Should Iran integrate into the global economy? How much will the economy improve with the lifting of sanctions? What will the policies of the next US president be, and what will this mean for Iran? With the recent victory of Donald Trump, these questions have become all the more important to Iranians.
