I have to agree with the croc. The US are deadly serious about taking out any potential nuclear weapon facility in Iran. If they don't attend to it, Israel will (only about 2 weeks ago Syria faced the reality of this). The new French president has aligned himself more to the US attitude on Iran but I think a large amount of what he said is to make Iran 'wake-up' to what might be on the cards. As far as the rest of the gulf is concerned, like the gulf wars of recent times it would certainly be extremely unsettling if your living in the region. Hopefully none of this will happen but it is a very real possibility in my opinion.
