Chergh,
I am an American and for the most part I agree with your assessment of the situation. Everything except your belief that Iran does not presently have the resources to build a bomb and would not use it unprevoked if they did.
A pre-emptive strike at this time would be foolhardy in the extreme. There is no doubt in my mind about that. But everything short of that needs to be done to try to eliminate the possibility of Iran (or any other country at this point) from joining the nuclear community. That would include "stable" countries. Why? Because the more nuclear weapons out there, the greater the chance that they will be used.
I lived the days of MAD. I worked at SAC HQ and worked in the underground command post, watching war simulations and the destruction of the world. I still get nightmares. Right now we have pulled back a bit from the brink and I do not want the meager progress we have made in this to be threatened, especially from a reactionary third world country such as Iran. Iran is fortunate in that their leadership, while religious zealots who spew lots of hot rhetoric, seem to be mostly sane. Not the case in North Korea at all. A 5th world nation tettering on the brink of starvation and collapse, with a totally irrational leader who has several nukes at his disposal. Yes, if we can stop Iran from building Da Bomb, we need to do so. If we need to strike pre-emptively and decisively in North Korea with a certainty of eliminating those bombs (not a chance) then we need to do so there as well.
It is not a question of terrorism, religion or anything else as it is a question of attempting to assure the survival of the human race. The stakes cannot be higher for us.
