I don't know what a bugbear is, but I know what Iran is and so does our government and the normal people who live there. Iran brings it's own troubles on itself by meddling in affairs that don't concern it. Israel does not care for Iran and wouldn't acknowledge it's existence if Iran kept to itself. American 'meddling' has been due to direct conflicts of it's own interests and, what I suspect you're alluding to, due to the Cold War. Iran's attack on U.S. Servicemen in Saudi Arabia was not a defensive action, or an act of protecting a resource, it was a petulant act of vengeance. You must have me mistaken with someone else, I'm not losing any sleep. I can simply recognize a situation and the proper context of it without interjecting my own emotions into it.
