that Tehran be "held accountable" for seeking to build nuclear arms in violation of its agreements. In June 2005, the US secretary of state Condoleezza Rice required former IAEA head Mohamed ElBaradei to either "toughen his stance on Iran" or fail to be chosen for a third term as IAEA head. The IAEA has on some occasions criticised the stance of the U.S. on Iran's program. The United States denounced Iran's successful enrichment of uranium to fuel grade in April 2006, with spokesman Scott McClellan saying, they "continue to show that Iran is moving in the wrong direction". In November 2006, Seymour Hersh described a classified draft assessment by the Central Intelligence Agency "challenging the White House's assumptions about how close Iran might be to building a nuclear bomb." He continued, "The CIA found no conclusive evidence, as yet, of a secret Iranian nuclear-weapons program running parallel to the civilian operations that Iran has declared to the International Atomic Energy Agency," adding that a current senior intelligence official confirmed the assessment.

One Iranian reformer said after the office opened that many "partners are simply too afraid to work with us anymore", and that the office had "a chilling effect".

The U.S. Nuclear Posture Review made public in 2002 specifically envisioned the use of nuclear weapons on a first strike basis, even against non-nuclear armed states. Investigative reporter Seymour Hersh reported in 2006 that the Bush administration had been planning the use of nuclear weapons against Iran. When specifically questioned about the potential use of nuclear weapons against Iran, President Bush claimed that "All options were on the table." According to the Bulletin of the Atomic Scientists, "the president of the United
