Iran.
Iran seem to be trying to develop a nuclear weapon, as has Pakistan. So. Should Irans nuclear plans be destroyed ? If so, why not Pakistan's too ? Both are islamicist countries that embrace that idiotic view of the world, that we are all muslims, and those that renounce it deserve to die. So, if us in the West destroy Iran's nuclear plants, what will Pakistan do ?
Thinking of this as a soldier, if I was the Iranians I would expect an attack, and move/hide/pre-empt by maybe doing what I built the weopons for, such as attacking Israel, as an attack on Europe is just about impossible, and an attack on the US certainly is. So why develop a nuclear weapon ? The Israelis and South Africans did as a means of defence, but why do that in Iran ?
