So we've got rhetoric and the 'it would be bad if they had nukes' argument. I'm dismissing the rhetoric flat out. If the nations of the world always reacted based on rhetoric, we would probably all be ash at this point.

While the reports on whether they're even pursuing nuclear weapons or are even close are pretty conflicting from what I've seen, let's say they did acquire them. What then?

Is Iran someone we consider to be just crazy enough to use them? And if so, what is that assumption based on?
Or is the real concern a matter of Iran then being able to better project their influence throughout the middle east with less options available to Israel and her allies to do something about it?

And I'm sorry to de-rail this thread. That statement from the White House stinks of being a part of the anti-gun movement. I personally don't think that Norway fool would have gotten 1/10 as far in the US as he did over there. Unless, of course, he was in some gun-free zone. Campus, etc. Imagine that.
