27,000 nuclear warheads -- like slavery or genocide

UN nuclear watchdog chief Mohamed ElBaradei said in his acceptance speech of the 2005 Nobel Peace Prize that the world had 27,000 nuclear warheads and "to me, that is 27,000 warheads too many".
"The hard part is how do we create an environment in which nuclear weapons -- like slavery or genocide -- are regarded as a taboo and a historical anomaly?" ElBaradei said.
