Probably in all of it. Iran wouldn't have a MAD arsenal, they'd have a small handful that they could pop on a ballistic. We know we can shoot down Iran's missiles. And we know they can't reach America. I'm entirely unconvinced that we wouldn't have launched an attack on Iran even if they had nuclear weapons, because we think we can intercept them, and if we can't, they aren't hitting the homeland.

And on the off chance this defense doesn’t work? No system is perfect. Put another way, would the risk calculation for an attack on Iran be as easy as it is right now?

The point of having nuclear capabilities is to make the risk calculation more difficult. It doesn’t mean you need to have state of the art capabilities.

    Someone in the Middle East gets hit.

    The risk calculation isn't easy today. Nukes would make it harder. But I'm pushing back on the notion that it would make it a non-starter.

    (MAD arsenals and long-range ICBMs, on the other hand, make it a non-starter.)

The difference between shooting down a conventionally armed missile and shooting down a nuclear armed missile is that the former will explode in the air or not at all, whereas the latter is quite likely to still be able to detonate when it hits the ground.

    If they’re using a novel, supercritical core mechanism, maybe. Otherwise, unlikely. (You would get fallout instead.)
