I most earnestly hope that the 'bomb-the-sh*t-out-of-Iran' brigade are firmly slapped into a dark, padded room by those in power with a few brain cells.
If a single bomb is dropped on Iran by any western power, the face of the western economies will radically change for the worse. Think about it.
The Iranians [and their sympathisers] will drive the price of oil through the roof by reducing production or restricting delivery. They can close the Strait of Hormuz by threats of [or actual] attacks on tankers, thus stopping the flow of oil. Alternative supply sources do not have the capacity to fill the void; what they do have will cost an arm and a leg and there will be an international bunfight as countries work to obtain supplies for themselves.
The cost of everything will rocket skywards, because oil is involved in all aspects of consumer life. Inflation will take off, and everyone in this country will be affected to some degree.
And the Iranians know it.
Still want to take the risk?
