intends to develop nuclear weapons, but believes Iran could at least be keeping the option to develop them open. Mossad Chief Meir Dagan was more cautious, saying recently that it would take the Iranians until 2014. German, French, and British intelligence said that under a worst-case scenario it would take Iran a minimum of 18 months to develop a nuclear weapon if it chose to build one, and it would have to first purify its uranium and weaponize its uranium. An anonymous source in the German Foreign Intelligence Service (BND) whose rank was not provided has gone further and claimed Iran could produce a nuclear bomb and conduct an underground test in 6 months if it wanted to and further asserted that Iran had already mastered the full uranium enrichment cycle, and possessed enough centrifuges to produce weapons-grade uranium. Physicists said that if Iran were to choose to develop a nuclear weapon, it would have to withdraw from the International Nuclear Non-Proliferation Treaty and expel International Atomic Energy Agency inspectors from the country. George Friedman, head of the global intelligence company Stratfor, has said Iran is "decades away" from developing any credible nuclear-arms capacity. On 12 February 2010 US think tank expert David Albright, the head of the Institute for Science and International Security, said in a report that Iran was seeking to "make sufficient weapons-grade uranium". An IAEA report issued 8 November 2011 provided detailed information outlining the IAEA's concerns about the possible military dimensions of Iran's nuclear program, noting that Iran had pursued a structured program or activities relevant to the development of nuclear weapons. On 30 April 2018, Israeli Prime Minister Binyamin Netanyahu revealed thousands of files he said were copied from a "highly secret location" in Teheran which show an Iranian effort to develop nuclear weapons between 1999 and 2003. On 1 May 2018 the IAEA reiterated its 2015 report, saying it had found no credible evidence of nuclear weapons activity in Iran after 2009. In 2021, a group of former Republican officials including ex-CIA director James Woolsey, wrote in the National Review that "Iran probably has already the atomic bomb," citing past detection failures by U.S. intelligence and the IAEA. IAEA The International Atomic Energy Agency (IAEA) is an autonomous international organization that seeks to promote the peaceful use of nuclear energy and to inhibit its use for military purposes. On 6 March 2006, the
