However, defining a common view about how to advance practical measures that will prevent nuclear terrorism is not so easy. When it comes to nuclear security, it has always been difficult to go from statements to actions.

Beijing has nothing to fear from IAEA security procedures or real-life, real-world tests of security at its nuclear sites.

Washington-Moscow relations may be strained over Ukraine, but the countries must still work together

In the past six months, President Barack Obama has taken three major steps to protect the world from nuclear terrorism and advance the disarmament agenda. First, during his April speech in Prague, he outlined his arms control and nonproliferation objectives and announced a U.S.-led international effort to secure all of the world's vulnerable nuclear materials within four years.

An unofficial gathering held once a year plays a crucial role in government preparedness for nuclear disasters. These are the experts who plan for the aftermath of some of the worst imaginable radiological emergencies.

The long-awaited report of the third Nuclear Posture Review is now scheduled for delivery to Congress on March 1.

In considering the implications of Fukushima for the 2012 Seoul Nuclear Security Summit, many experts in the United States would probably argue that there are none -- their fundamental point being that it is a security summit, not a safety summit.

When the Group of Eight (G-8) last gathered in Canada in 2002, the summit meeting was an unarguable success for the future of weapons of mass destruction (WMD) security. The leaders launched a multilateral initiative, known as the Global Partnership against the Spread of Weapons and Materials of Mass Destruction, and pledged $20 billion over 10 years to help Russia destroy their WMD stockpiles.

President Barack Obama's upcoming Nuclear Security Summit has the potential to become a defining moment for international security in the twenty-first century, especially after the recent release of the U.S. Nuclear Posture Review.

If a nuclear deal is reached, the Nuclear Security Summit should add another seat at the table

A few weeks ago, an anti-nuclear group breached security fencing at the Kleine Brogel Air Base in Belgium. Undetected, the group spent more than an hour on a military base where U.S. nuclear weapons are supposedly stored. Worse yet, they then uploaded to YouTube a video showing exactly how they exploited Kleine Brogel's security weaknesses. Replace peace activists with terrorists and the results could be devastating.
