Maybe someone should post a thread entitled "The Case for Getting Saudi Arabia to Invade Iran."
Also...nobody is mentioning the idea that we let Saudi Arabia or Israel attack first and then come in when Iran launches a missile over Iraq toward Israel, with US forces fully prepared and just happening to be standing on the border (and Airborne troops just happening to be sitting on Iraqi and Afghani and Azeri airfields).
Of course, we can have a major insurgency crop up in Iran and Iran will know it is caused and equipped by the USA and attack us somewhere in the world and then the whole world will be OK with the quick regime change and revolution that then occurs.
Yeah, we'll use the newly formed 120th AA Division, the 12th Armored Division and the 212th Infantry Division and the 8th MEF...just for starters.
Maybe we should sign a mutual-defence treaty with Israel (if we don't have one already). Kind of like NATO in that an attack on Israel by another nation would be seen as an attack on the United States by that same nation and would be dealt with accordingly.
It just might (although I seriously doubt it) cause the wackos in Iran to pause just a second before launching a nuclear missile on Israel. It would, however, give us an airtight excuse to turn them into a parking lot if they did.
Just a thought...
