Collecting potassium iodine is not going to save Americans, that’s for sure. The amount of preparation for the American people to survive would be next to extraordinary. Most people these days do not have what it takes, and certainly our government does not, either.

The thing is that even if the missile defense system works 100% successfully for a nuke approaching the United States, the electromagnetic pulse above is enough to disable all electronic devices in the US. Like the trajectory of the plume covers the vast majority of the US, no matter what direction the nuke comes from.

At the altitudes they would typically be intercepted at (for ICBMs amyways), it would likely be dispersed over most of a hemisphere and likely somewhat weak... until there are multiples.

what electromagnetic pulse? intercepting a nuke doesn't detonate it early like a conventional explosive; it most likely turns it into a dud.

The EMP blasts - likely multiple - that are precursor strikes for the city bombing.
