I don't know if you have noticed but Iran is run by nutcases and the situation with their nuclear plans could change this way of life as we know it,
Iran won't back down, the U.S can't back down unless they want to look weak, they are also abit proud and mad themselves so I only see the craziest war of all time infront of us now.
Seriously if you know anything about this current Iranian regime you'd know there is more chance of Bush becoming a muslim than Iran backing down from this.
If the U.S or Israel attack Iran, who's to say all the oil ports and points in the gulf will be wiped out before Iran is, yes Iran is that crazy, if they are going to go down, they will take the modern way of life with them, I have no doubts about that.
Iran will be backed by China/Russia so sanctions are worthless and will only unite the Iranians causing more 'terrorism' in the middle east and around the world, it would also cause a massive conflict between the U.S and China/Russia starting off a nuclear war for the worlds remaining oil supplies which would also mean the end of this way of life as we know it.
Oil running out of the ground has never been the problem, its when they start fighting for the remaining oil, thats when the shit hits the fan, it won't be only just those people in the middle east suffering for this, it will be all of us.
