This is what a typical attack on the U.S. would likely look like. Attack 1 is an attack that attempts to hit the U.S. silos in addition to other U.S. military and civilian targets. It's what would perhaps be used in a first-strike scenario. Attack 2 assumes that the land based U.S. missiles have already launched, and only targets military and civilian targets, but doesn't worry about targeting U.S. land based missile silos.

The casualties figure is immediate, and doesn't include things like the breakdown of society -- this is just the casualties estimated from the actual war itself.
