Spitballs!
As much as it would be a lovely idea to see an end to the Iranian nut-jobs dreams of having Nukes with an all out attack on their facilities by either the U.S or Israel. Its really not going to be that simple (When is it? :D )
You see, recently the Iranians have purchased a quite high number of Russian-made 3M-82 Moskit anti-ship cruise missiles (NATO designation: SS-N-22 Sunburn.
The Sunburn can deliver a 200-kiloton nuclear payload, or: a 750-pound conventional warhead, within a range of 100 miles, and it travels at Mach 2. Basically its designed to sink a carrier.
The US Navy's only defense against the Sunburn missile is to detect its approach well ahead of time. For this purpose US AWACs radar planes assigned to each naval battle group are kept aloft on a rotating schedule. The planes "see" everything within two hundred miles of the fleet.
Trouble is the US navy operating in the Gulf faces a serious challenge that is unique to the coastal, environment. A glance at a map shows why: The Gulf is nothing but a large lake, with one narrow outlet, and most of its northern shore, i.e., Iran, consists of mountainous terrain that affords a commanding tactical advantage over ships operating in Gulf waters, should they have mobile launchers in those mountains things could get tricky.
Mind you they'd be even trickier if the Nut-jobs got nukes and tipped the Sunburns with them, they could hold all shipping in the gulf to ransom in that event.
Difficult times ahead I believe.
