Peaceful resolution - Iran Nukes
I think it wouldn't hurt to basically lay it on the line and say,
"OK... It's OK if you develop nuclear capabilities. However, if the US or any of our allies get nuke'd, we aren't even going to bother to find out who did it, we are going to level your country and everyone in it."
Of course their alternative would be to rethink whether they want nuclear capabilities since not having them would clearly exempt them from being the one's who pulled the trigger.
I'm surprised that one of the hard left or right wingers hasn't commented on this issue. It's actually a very challenging political problem. You see, Israel will not allow Iran to have nuclear weapons. Period. They are extremely vulnerable and they know just a few suicide nuclear bombers could lay waste to their entire country. Being our main ally in the middle east, we can't really allow them to fight this thing alone.
This is one of those, "nothing good will come of this" type of situations. Should we get involved, should we happily ignore the problem, or approach it diplomatically? Personally I don't think diplomacy is going to work. However, I don't really think we should continue fighting the worlds problems alone either.
