Tehran says it will expand its atomic work by installing 3,000 centrifuges - devices used to enrich uranium. Experts say with 3,000 centrifuges in place, Tehran could make enough material for at least one warhead a year.



Notwithstanding that Iran signed the Nuclear Non-Proliferation Treaty on July 1, 1968 and ratified the treaty 19 months later, the U.S., France, Germany, Russia and the United Kingdom have accused Iran of a clandestine intention to develop nuclear weapons.



A 2005 assessment by the International Institute for Strategic Studies, a prestigious London, U.K.-based think tank, concluded "If Iran threw caution to the wind, and sought a nuclear weapon capability as quickly as possible without regard for international reaction, it might be able to produce enough highly enriched uranium for a single nuclear weapon by the end of this decade, assuming no technical problems. More plausible development programs Iran could choose to follow would take over a decade."



The future U.S. Secretary of State for Defense, Robert Gates, in a hearing in front of the Senate Wednesday, said that it was impossible to rule out the possibility of an Iranian nuclear attack against Israel. "If Teheran acquires a nuclear bomb, no-one can guarantee that it will not be used to wipe Israel off the face of the map (the words of Iranian president Mahmoud Ahmadinejad)", he said.
