For the moment I suspect Iran is not really in the game. Iran is benched.The Israelis don’t seem worried about it and the drumbeat for attacking has muted.Iran won’t be up and running again for a while, maybe a few years. Stuxnet has been very expensive. In the meantime if the US were actually intent on survival we would be drilling for oil and gas an in all promising areas in and around North America and going full tilt for nuclear plants. The only way to put a lengthy hiatus to the Islamic War is to cut off the funding of it, i.e. quit buying the oil. We have the capability- nuclear and the oil and gas in the ground and offshore, - to be self sufficient and once we are self sufficient we can squeeze the oil in the ME so that it does not flow to Europe and less goes to China. The War will not end so long as there are both Moslems and infidels alive in the world but when Islam has not sufficient resources to wage war, it will dry up for a time. The alternatives are eventual conquest and Islamicization, or military and economic destruction of the primary actor(s) in the Moslem world- Iran, Arabia, and probably Pakistan.
They don’t have to be in the game just yet. We’re going to lose Europe in the meantime to the muzzies.
