Nuclear weapons fear

Nuclear weapons by Iran is not so frightening, not for the US, at least. Iran cannot and will not use it in its own neighborhoods without harming itself. But of course it can export the technology to rogue nations who are suicidal. Iran's history has no such tendencies. What one needs to worry is how good Iran has got at other weapons like missiles which can do real time harm to US presence in the middle east. America's interests lie in making friends with Iran which in my opinion is a progressive nation in the region compared to Saudi Arabia or even Kuwait. Also Iran benefits by making friends with America because it will have access to technology it needs to progress. Yes there are other injustices happening in the world but the solution to each problem is different and not quite connected.
