Actually, since Iran launching a nuke at a heavily populated area (say, bigger casualty figures 'achieved' than hiroshima) would mean pretty much the end of the world for human civilization, I don't think it's unreasonable for Iran to launch an intercontinental nuke. Think, for example, if all the social welfare programs that they offer are no longer relevant (bad example actually, they probably don't have much in the way of such programs in Iran). Then they could pour all that funding into getting a nuke. I mean, what the hay, they could even just steal one using an agent inside a country that does have one.
Anyway, it may be useful to note that it would be pretty easy, in comparison, for Iran to threaten Israel with a short-range one. It's in their freakin' constitution. That may actually be better for the world - maybe Israel would be able to defuse the situation more or less by itself without anyone getting nuked.
No. No. No. Iran will
not get ICBM capability. Hell, it'll be at least 3 years before they even get nukes, let alone develop a platform for launching at another continent. But, okay, let's say that they do
somehow get an Nuclear-tipped ICBM through the ludicrous economic policies you described or simply 'stealing one' a la Dr. Evil; why the f*** would they nuke anyone?! Honestly, the only people they would want to nuke would be Isreal, and if that were ever a real posibility, Isreal would turn Iran into a f***ing crater at the drop of a hat. If, for some reason, they suddenly get a brainstorm to throw a nuke at another nation at random, they'll live just long enough to see about 200 nukes coming at them from all directions. If the thought of nuking someone even crosses their minds, they can kiss their little portion of the planet goodbye, so why the f*** would they risk it?
Even
if Iran gets the bomb, it will
only be short range, they have absolutely no possible way of acquiring intercontinental weapons short of buying one off Russia or something [which is still unbelievably far-fetched], which would lead to pre-emptive strikes the second any major western intelligence organisation gets wind. I am so sick and tired of everyone blowing this crap utterly out of proportion saying 'zomg, Iran has teh nukes, they're gonna nuke everyone!! Oh noes!!', when in reality they most likely only want nuclear weapons so they have a trump card should the US or another nation get wiley and try to invade [a la North Korea].
Unless you live in or around the Middle East, there is absolutely
no chance of a Nuke getting dropped on you, so the only person allowed to be worried is probably Sarno.
