Re-examining Japan's nuclear history could not only help the country come to terms with the Fukushima disaster, but help it find a future without the US nuclear influence that has shaped its past.
The nuclear safety "stress tests" planned for Europe should be expanded to include tests that evaluate the security of nuclear materials around the world.
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.
Since the 1970s, Japan has turned to nuclear as a secure source of energy. But this security has a double meaning.
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.
After Three Mile Island, the US failed to reform the Nuclear Regulatory Commission or force improved containment designs. The tragedy in Japan is a chance not to make the same mistake twice.
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.
Warsaw received the U.S. administration's decision on the European missile defense plan with mixed feelings. And despite suggestions of a new program with new opportunities, future U.S.-Polish cooperation won't be easy.
The six-year-long war has been a bonanza for arms traffickers, with billions of dollars in sales and decreased government controls. Not since World War II have arms sales been so profitable.
While details about Pyongyang's upcoming rocket launch remain scarce, a review of North Korean missile capabilities demonstrates possible launch-vehicle configurations.
To foster a productive dialogue with Pyongyang, President Barack Obama must make tangible promises and then keep them.
The first step in disarming North Korea--energy aid. Here's how the United States, South Korea, China, Japan, and Russia hope to provide it.
Despite shutting down North Korea's plutonium production complex, complete denuclearization remains a formidable goal.
The Scud, a descendent of World War II-era German V-2 rockets, is the ballistic missile of choice for world dictators and would-be proliferators. An explanation of how the technology spread.
It's been 45 years--how about trying incentives to get North Korea to cooperate with the international community?
Which claims about Pyongyang's nuclear weapons program are on target? A technical analysis of often conflicting data and news from one of the world's foremost experts.
Tales of Pyongyang's imminent collapse are legion and certainly not new. For independent observers, it's hard to know what's true. One thing you can count on, a continued standoff.
The threat to the United States from developing world missiles has been grossly exaggerated. Thus, the billions of dollars spent for SDI would offer protection from friends, not enemies.
