However, I also don't think that we should actively prevent Iran from gaining nuclear technology; why? Because it makes the world a safer place. Yes, that seems like an inherent contradiction, but I would beg to differ. We were much safer during the Cold War than we are now.
Despite our fears of getting blown up, no one but a completely insane ruler would inflict MAD on the world, and even in totalitarian states, there is the fact that it is filled with people just like you and me. Iranians and North Koreans are not robots. They have families, homes, children just like we do. And rest assured, they do NOT want them to die in nuclear destruction.
Now we have no nuclear deterrant, so there is much less reason for us to negotiate. Thus, we threaten and bully, and thus, they fight back in the most distasteful, but for them, the only way: terrorism.
I hope you'll take the time to read this post, instead of just taking snippets out of them and bashing it; either take the thing as a whole or put me on your ignore list, but don't take one sentence out of a paragraph and then bash that; it's something we've seen far too often and leads only to flame wars.
