US intelligence predicted in August 2005 that Iran could have the key ingredients for a nuclear weapon by 2015. On 25 October 2007, the United States declared the Revolutionary Guards a "proliferator of weapons of mass destruction", and the Quds Force a "supporter of terrorism". Iran responded that "it is incongruent for a country who itself is a producer of weapons of mass destruction to take such a decision." Mohamed ElBaradei, director of the IAEA at the time, said he had no evidence Iran was building nuclear weapons and accused US leaders of adding "fuel to the fire" with their rhetoric. Speaking in Washington in November 2007, days before the IAEA was to publish its latest report, Israeli Deputy Prime Minister Shaul Mofaz called for ElBaradei to be sacked, saying: "The policies followed by ElBaradei endanger world peace. His irresponsible attitude of sticking his head in the sand over Iran's nuclear programme should lead to his impeachment." Israel and some western governments fear Iran is using its nuclear programme as a covert means to develop weapons, while Iran says it is aimed solely at producing electricity. For its part in the conflict-ridden Middle East, Israel is a member of the IAEA, but it is not itself a signatory to the Nuclear Non-Proliferation Treaty, and is widely believed to currently be the only nuclear-armed state in the region.
