A new U.S. assessment found that U.S. strikes on three Iranian nuclear sites in June largely destroyed the Fordow site, setting back uranium enrichment work by as much as two years, but that the other two sites were not as badly damaged. Iran may be able to resume uranium enrichment at these locations in the next several months, according to the assessment. The U.S. and Israeli government have been discussing whether additional strikes on the two less damaged facilities could be necessary if Iran does not agree to resume nuclear negotiations with the United States, or if there are signs that Iran is trying to rebuild at those locations.
