NEW YORK - The head of United Nations nuclear watchdog says he should have made more noise to prevent the US-led attack on Iraq for which the information supplied by his agency was misused. I should probably, before the Iraq war, have screamed and howled harder and louder to prevent people from misusing the information that was made available by us, Mohamed ElBaradei, director general of the Vienna-based International Atomic Energy Agency (IAEA), said in an interview published in the latest issue of Time Magazine. The 67-year-old Egyptian, who is serving his third and last four-year term ending in November, was responding to a readers question to cite any bad judgment call on his part during his tenure as IAEA chief. Asked what was the least satisfying moment of his career, ElBaradei pointed to the launch of the Iraq war. That hundreds of thousands of people lost their lives on the basis of fiction, not facts, makes me shudder. While asserting that every country has the right to develop peaceful nuclear technology, ElBaradei expressed doubts about whether Iran was pursuing a nuclear weapons programme as alleged by the United States and its European allies. We are not sure that Iran is pursuing nuclear weapons. The jury is still out. What we know is that there are still a number of questions that Iran needs to clarify. I fully support (US President) Barack Obamas initiative to engage in a comprehensive dialogue to build trust. He also chose Obama as one of the world leaders on the right track on nuclear policy. Obama... is changing the conventional wisdom... saying that we have to have a security system that does not depend on nuclear weapons.
