I have read that a Neutron bomb is much smaller and the radiation is just a fraction of a other nuclear devices. The half life of selenium is 28 years. Some reports say you can enter the nuclear blast region after 7 days for a Neutron bomb. These would be used to target the vast area of Iran's nuclear development sites.

Iran is so large there would be no fallout to other countries especially if the more inner regions are targeted. I can see the nations of the world coming against Israel when Israel does this, and they surely will. Israel cannot afford even one nuclear explosion on their territory, otherwise they are done for. The president of Iran says Israel will be destroyed soon.

Healing takes place after the nations realize Israel belongs as the center of all nations from where Christ reigns when the Tribulation ends, and His overcomers reign with Him. Israel does not get to reign as kings and priests. They are just the location from where Jesus reigns form the 3rd Temple.
