I think you hit it right on the head, Hipshot.
Depending on the source, Iran either has the genesis of nuclear weapons technology, or it already posseses the technology. It really doesnt matter what stage they are currently in. The end result is simple-one way or another, today or tomorrow, they can and will hurt us.
They also have several decent platforms to deliver the weapons they can build. From rocket propelled torpedoes to three stage missiles knocked off from the North Koreans, they have a variety of delivery means they can use to put the hurt on us when they choose to do so.
They have a genocidal nut for a leader....enough said. Although he claims he is doing the will of God, his own worlds show him to be a despot and a tyrant. This nut also hates us with a passion.
Anyone who knows anything about history knows one thing- this only has one logical conclusion unless something extraordinary happens soon. Unfortunately, there are not too many people who this type of knowledge in our society today, and they are immediately shouted down by people with agendas and marginalized.
We definitely live in dangerous and interesting times.
It was reported two or three months ago that they, at nontrivial effort and expense, replaced the nosecones on some of their missiles, with the replacements having slightly modified internal dimensions.
Now, you tell me why they'd go to all that work and spend all that money, for a modification so trivial that, if used with a conventional explosives payload, would result in a null improvement in performance.
I find it particularly ominous that their recent cocky arrogance and belligerence occurred in the same timeframe as their nosecone replacement project.
