30 more countries could have nukes soon:
"The knowledge is out of the tube ... both for peaceful purpose and unfortunately also for not peaceful purposes," ElBaradei said.
"It's becoming fashionable for countries to try to look into possibilities of shielding themselves ... through the possibility of nuclear weapons," he said, adding: "Another 20 or 30 would have the capacity to develop nuclear weapons in a very short time."
Indirectly criticizing nuclear weapons states, ElBaradei said it was illogical for them to maintain their atomic arsenals while urging others not to acquire such arms.
He also obliquely took some of them to task for not signing or ratifying the Comprehensive Test Ban Treaty, suggesting their endorsement of the 1996 pact "would have changed the behavior of North Korea, maybe."
The treaty, which prohibits all nuclear explosions, will not take effect until it has been ratified by 44 states that possess either nuclear reactors for power-generation or research. So far 34 have ratified it. Holdouts include the U.S., China, India, Pakistan, Israel and North Korea.
