You know what ... that was educational.
What I learned is that the nuclear threat to our large cities is much LESS than I expected. Much less.

Try setting the detonation level to 20kT, or even 100 kT, and centering it on Los Angeles. Only a small fraction of the city is destroyed. The bottom line is that if our citizens stayed calm and responded well - there would be more than adequate emergency facilities and hospitals left to cope with the injuries and casualties. That's actually very reassuring. Americas big cities are so BIG that it's pretty much impossible to take them out ... except by a widespread natural disaster (like a huge earthquake or hurricane).

Maybe the real conclusion here is that the US media, and the "climate of fear", that seems to pervade our thinking needs to be swept away. We are more in danger from widespread fear, confusion and panic - than we are from the nuclear threat.
