Good for them. This is an existential crisis for them....and the US and the rest of the West. Only Israel seems to understand this. Basically the whole Western World needs to literally bomb Iran back into the Stone Age. Iran is a mahdist theocracy. They will absolutely provoke a world apocalypse if they can. That is absolutely their ultimate aim. The ONLY way to control such a regime, and look up the term "mahdist" (assuming I spelled it correctly), is to absolutely destroy it. Winston Churchill personally fought the last "Mahdi" at Omdurman. If such a regime obtains nuclear weapons, they absolutely will use them, and there is NO deterrence that will work. They WANT to provoke the ultimate holocaust for all of mankind. It IS the essence of their religion. Look it up if you don't believe me.
