Iran has enough enriched uranium for four nuclear bombs
03 June. By April 2011, Iran had accumulated a quantity of U-235 that can be enriched in short order to sufficient 90 percent (weapons grade) uranium for producing four nuclear bombs, steadily stockpiling the material in secret from 2008.. This was revealed by the Wisconsin Project on Nuclear Arms Control, America's scientific watchdog on world nuclear weapons production in its latest report of June 2 – hence the revived military option dispute. By breaking the IAEA seal at the Natanz enrichment plant, Iran gained another 6-7 months for concealing the work there.
