They may not be a threat to the west but they are a real threat to Israel currently by supporting their oppenents and when possible by direct action themselves according to the the words of Mahmoud Ahmedinejad. Remember Israel have nukes and will not hestitate to use them if they feel threatened and if that happens then the middle east goes bang followed closely by the rest of the planet!
What is it you think the Americans should be doing about Israel?Much as I dont Want Iran to get them, it irritates the f*** out of me when you have the Americans wagging fingers about non proliferation without so much as a word about Israel, I'd blame it on the jewish lobby over there if I hadnt been repeatedly told it's non existent.
I imagine Israel will bomb Iran before they get nuclear weapons, I who can blame them.
