IAEA policy against "telling the whole truth" about Iran and pointed out other factual errors, such as a claim that Iran had enriched "weapons-grade" uranium. John Bolton, then US ambassador to the UN, said on 31 August 2006 that he expected action to impose sanctions to begin immediately after the deadline passed, with meetings of high-level officials in the coming days, followed by negotiations on the language of the sanctions resolution. Bolton said that when the deadline passed "a little flag will go up." "In terms of what happens afterward, at that point, if they have not suspended all uranium enrichment activities, they will not be in compliance with the resolution," he said. "And at that point, the steps that the foreign ministers have agreed upon previously ... we would begin to talk about how to implement those steps." The five permanent members of the Security Council, plus Germany, previously offered Iran a package of incentives aimed at getting the country to restart negotiations, but Iran refused to halt its nuclear activities first. Incentives included offers to improve Iran's access to the international economy through participation in groups such as the World Trade Organization and to modernize its telecommunications industry.

IAEA officials complained in 2007 that most US intelligence shared with it to date about Iran's nuclear program proved to be inaccurate, and that none had led to significant discoveries inside Iran through that time. Through 2008, the United States repeatedly refused to rule out using nuclear weapons in an attack on Iran. The US 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.

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, Bush "directly threatened Iran with
