» Nuclear summit:
Obama, leaders cite progress, mixed with fears
World leaders warn of a persistent and harrowing threat of terrorists getting their hands on a nuclear bomb.
Washington — World leaders declared progress Friday in safeguarding nuclear materials sought by terrorists and wayward nations, even as President Barack Obama acknowledged the task was far from finished.
Closing out a nuclear security summit, Obama warned of a persistent and harrowing threat: terrorists getting their hands on a nuclear bomb. He urged fellow leaders not to be complacent about the risk of catastrophe, saying that such an attack by the Islamic State or a similar group would “change our world.”
“I’m the first to acknowledge the great deal of work that remains,” Obama said, adding that the vision of disarmament that he laid out at the start of his presidency may not be realized during his lifetime. “But we’ve begun.”
Despite their calls for further action, the roughly 50 leaders assembled announced that this year’s gathering would be the last of this kind. This year, deep concerns about terrorism were the commanding focus, as leaders grappled with the notion that the next Paris- or Brussels-style attack could involve a nuclear weapon or dirty bomb.
Obama said of the terrorists: “There is no doubt that if these madmen ever got their hands on a nuclear bomb or nuclear material they most certainly would use it to kill as many innocent people as possible.”
So far, no terrorists have obtained a nuclear weapon or a dirty bomb, Obama said, crediting global efforts to secure nuclear material. But he said it wasn’t for lack of the terrorists trying: al-Qaida has sought nuclear materials, the Islamic State has deployed chemical weapons and extremists linked to the Brussels and Paris attacks were found to have spied on a top Belgian nuclear official.
Throughout the two-day summit, growing fears about nuclear terrorism tempered other, more positive signs of the world coming together to confront the broader nuclear threat.
The U.N. Security Council members who brokered a sweeping nuclear deal with Iran held up that agreement as a model for preventing nuclear proliferation, as they gathered on the summit’s sidelines to review implementation of the deal.
Obama also spent part of the summit huddling with the leaders of South Korea and Japan about deterring nuclear-tinged provocations from North Korea, in a powerful show of diplomatic unity with two U.S. treaty allies. Similarly, Obama’s sit-down with Chinese President Xi Jinping offered the two strategic rivals a chance to illustrate mutual concern about North Korea, a traditional Chinese ally.
Undeterred, North Korea only hours later fired a shortrange missile into the sea and tried to jam GPS navigation signals in South Korea — precisely the kind of act that South Korean President Park Geun-hye had warned would trigger even tougher sanctions and more isolation.
In signs of progress, though, the White House said Latin America and the Caribbean are now free of highly enriched uranium and praised Argentina by name for converting its remaining stockpile into a less dangerous form. Fissile materials like highly enriched uranium and separated plutonium are necessary ingredients to make nuclear bombs.
The United States, in newly declassified statistics, said its own national inventory of highly enriched uranium has dropped from 741 metric tons two decades ago to 586 metric tons as of 2013. And the U.S. and Japan announced that they had finished removing hundreds of kilograms of weapons-grade material from a Japanese research reactor and pledged to do the same at another.
But the absence of some key players, especially Russia, further underscored the lack of unanimity confronting global efforts to deter nuclear attacks.
