No, Cindy. Without exception means without exception. Neither radical Islam nor radicals of any sort should have nuclear weapons. Particularly Iran, North Korea, the USA, Pakistan, India,China,Russia,Great Britain, France and Israel should all be brought to understand that they have nothing to lose and everything to gain by putting any and all nuclear weapons they own or develop in the exclusive hands of a democratically elected international world police force, which would then exercise a nuclear blackmail and control monopoly to defend us all and stop anybody else ever again developing new weapons of mass destruction or egoistically threatening to destroy anybody.
If Iran or anybody else doesn´t want to see the sense in this, the rest would have the joint power to enforce nonconformist compliance.
