US national security agencies recognize the seriousness of the climate change threat. Why aren't America's other policymakers responding?
Before leaving office, Defense Secretary Gates criticized European NATO members for not appropriately sharing costs related to alliance defense obligations. His remarks raise an important question: Is it time to reconsider the deployment of nearly 200 US tactical nuclear weapons in Europe?
Long-term planning studies too often rely on initial cost estimates for major energy projects, rather than on actual costs. That can lead to poor decisions.
In the initial response to the Fukushima nuclear accident, some things did not happen soon enough while other things happened too quickly.
With bin Laden's death, the United States has the opportunity to shift strategy, take focus off terrorist groups, and re-engage on the real existential threats to the nation.
Malaysia is moving ahead with plans for its first nuclear power plants, but the country is even more divided over nuclear energy after the Fukushima accident.
On the 25th anniversary of Chernobyl, a nuclear physicist recalls the frenzied media coverage that followed the accident, and reflects on what has changed.
Debates over the health effects of various radiation doses are obscuring the real issue: No dose is safe or harmless.
The ongoing crisis at the Fukushima Daiichi nuclear power plant is not a cause for panic but rather an opportunity to improve safety worldwide.
The success of the CTBT's global monitoring system in response to the tragedy in Japan has demonstrated its effectiveness in responding to natural disasters, further evidencing its value to US and global security.
Japan faces prolonged anxiety and distress in its quest to find answers to the Fukushima disaster. One answer may be that a conventional back-up system was in the wrong place. There is much to learn.
In the wake of Fukushima, it may be time to broaden the scope of the Seoul 2012 Nuclear Security Summit to include safety issues as well as security.
The energy future must take into account the needs of the world's growing population and protect the future viability of the planet. And this does not come without risk.
Before this month's tragedy in Japan, many were confident that reactor design and safety had matured and catastrophic accidents were simply not going to happen. Fukushima has proven these assumptions wrong -- and it will have a number of implications for the energy debate.
With science unable to accurately determine major geologic events, a reassessment needs to be made of how much nuclear site planning relies on such predictions.
Releasing information about the status of the nuclear plants, the extent of the damage, and the risks of further radioactive emissions can serve to dampen negative commentary and worst-case speculation.
A review of how baby teeth studies that started in the 1950s could apply to the Comprehensive Test Ban Treaty today.
In striving toward the long-term goal of a WMD-free Middle East, short-term goals must be set.
