In May 2009, the EastWest Institute released a joint U.S.-Russian Threat Assessment on Iran's Nuclear and Missile Potential. The report concluded that there was "no IRBM/ICBM threat from Iran and that such a threat, even if it were to emerge, is not imminent." The report said there was no specific evidence that Iran was seeking the ability to attack Europe and that "it is indeed difficult to imagine the circumstances in which Iran would do so." The report said if Iran did pursue this capability, it would need six to eight years to develop a missile capable of carrying a 1,000 kilogram warhead 2,000 kilometers. The report said Iran ending "IAEA containment and surveillance of the nuclear material and all installed cascades at the Fuel Enrichment Plan" might serve as an early warning of Iranian intentions.
