This must be music to the ears of those who dream of Armageddon and impatiently await The Rapture. The Americans recently ran a war game simulation of what would follow an Israeli air attack on Iranian nuclear facilities. Apparently they were rocked by the predicted results - a regional war that would quickly drag America into its maelstrom.
It seems the Americans needed a war game simulation to realize that an Israeli airstrike on Iran would probably trigger an Iranian missile attack on one or more of the aircraft carriers the US Navy has cruising rather menacingly near Iran in the Persian Gulf. Who'da thunk it? That would, of course, be the act of war or Casus Belli that the hawks in Washington would need to then launch their own war on Iran.
American officials believe Israel would probably give Washington little or no advance notice of launching a strike against Iran. And, of course, there's no mention in this of the enormous havoc that would be caused within Iran from the nuclear debris of these attacks or how Russia and China could exploit the chaos or find themselves dragged into the conflict.
