Obama summit's goal: keep nuclear weapons away from terrorists

Noting that “the primary responsibility for action rests with individual countries,” Mr. Samore says a number of countries will announce measures they plan to take on behalf of enhanced global nuclear security. Chile will highlight the recent transfer of its remaining stockpile of HEU to the US for disposal, and the US and Russia will announce agreement on a long-stalled plan for each country to dispose of large amounts of plutonium.

But other experts note that nuclear security is not the priority for many other countries that it is for the US – and they say that as a result the US must be prepared to offer those countries incentives reflecting their priorities to get them to cooperate.

“If I were advising President Obama, I’d say you have to be prepared for some trade-offs with countries that don’t place the same priority on this issue that you do,” says Charles Ferguson, president of the Federation of Atomic Scientists in Washington.

A trade-off in priorities

“You have countries in sub-Saharan Africa with materials that are weapons usable, but for whom the priorities are more along the lines of development and feeding people and disease,” he adds. “So you’re going to have to offer something they want to get them on board, but I’m not sure there’s been that kind of linkage from the people in charge.”

Another factor that could stymie broad cooperation on nuclear materials security is that the “lockdown” approach “fails to recognize that these materials do have legitimate uses in both the civilian and military sectors,” in research laboratories, for example, Mr. Ferguson says. Securing loose nukes and keeping dangerous materials out of the hands of dangerous nonstate actors may be a legitimate priority, but achieving the goal will be more difficult if developing countries in particular get the sense that they are losing out and paying a price for the developed world’s security, he adds.

One way of bridging the developed-developing world gap on the issue, Ferguson says, is to move beyond “individual country” actions to strengthening the multilateral aspect of steps to be taken. The International Atomic Energy Agency, or IAEA, the UN’s nuclear watchdog, has a relatively recent nuclear security function, but funding for it is voluntary and at the whim of member states.

“If you put the IAEA’s nuclear security department on a regular budget,” says Ferguson, “you’d have a sure way of putting a bigger international effort behind this four-year plan.”
