The GCC do not want Iran to get Nuclear weapons.
Iran is a signatory to the non proliferation treaty - so they have to stand by it. US and Russia have reduced weapons, UK is planning to. We need to rid the world of such weapons not let them become more widespread.

Just my thoughts on the matter.

"Deaths in the Bible. God - 2,270,365
not including the victims of Noah's flood, Sodom and Gomorrah, or the
many plagues, famines, fiery serpents, etc because no specific numbers
were given. Satan - 10."
