President Barack Obama said Friday that the world faces a persistent and evolving threat from terrorists who are eager to unleash a devastating nuclear attack. “It would change our world,” he said.
Hosting his last nuclear security summit, said the world has measurably reduced the risk of nuclear terrorism by taking “concrete, tangible steps.” He said no terrorists have thus far obtained nuclear material, and he praised recent moves by Argentina, Switzerland and Uzbekistan for getting rid of their stockpiles of highly enriched uranium.
