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.
