Invasion? ASB. Our Islamic dictator who's running the show behind the scenes from the White House will invite them over.

In seriousness, the only way this can have a half chance of happening is if 'Iran' becomes a nuclear powered Islamic caliphate by 2050, stretching vaguely from Arabia to somewhere beyond its eastern border but stopping short of India.

Now you have a 9% chance of an Islamic invasion of the US in 2050, depending on how the rest of the world is doing by then. Having a superpower China by then as an ally would be useful. Start from there, and maybe the percentage can go into double digits.

You're kidding? Let's see...all the 'layers' the Iranians have to get through.

First layer: USAF Strategic Air Command. Second largest stockpile of nuclear weapons in the world, capable of delivery across the globe on 24 hour notice via strategic bomber or ICBM.

Second layer: USN Second, Fourth, Fifth, and Sixth Fleets. A total of five CVNs which, along with escorts, outweigh the Royal Navy, Marine Nationale, VMF, and PLAN combined.

Third layer: USAF Tactical Air Command. Top of the line aircraft, top of the line pilots. Also, only 5th generation fighter currently in service.

Fourth layer: US Army and US Marine Corps. Big. Fucking. Bad. Toys.

Fifth layer: Militia, local police, and Redneck Joe. At this point, it's not even funny.
Actually, the Strategic Air Command doesn't exist anymore. It was dismantled after the Cold War. It's replacement is the Air Combat Command. No, I'm not kidding.
 
Neither does TAC - ACC is the result of merging it and SAC. Strategic Command now handles the nuclear warfighting mission with both USAF and USN assets. Air Force Global Strike Command is responsible for the control of USAF nuclear capable assets (B-52s, B-2s and the Minuteman III force), making it effectively the successor to SAC.
