Speculation has been rife for some time now over a possible US and/or Israel attack on Iran to stop its nuclear program. But an attack on Iran will certainly not be a simple mission.

For one, too many targets in Iran have to be attacked to stop its nuclear program. An Oxford Research Group (ORG) report, issued in July, classifies the targets into six categories: uranium enrichment plants, the Esfahan uranium conversion facility, nuclear research and development sites, factories making supportive equipment, military bases with missiles, and physics, engineering and related university departments and their employees.

Since the targets are spread over Teheran, Natanz, Tabriz and Esfahan, it would be very difficult to carry out military strikes on them simultaneously. And even if attacks are carried out simultaneously, the US or Isarel cannot avoid deaths and injuries to a huge number of civilians.
