I think I remembered reading that if the first Civil War's losses were extrapolated to our present day population, deaths from a similar civil war today would be over 9 million.

I believe that figure of 9 million, is understated..

Because:
There are 10s of million Armed Americans..
There are millions of combat veterans in the U.S., or veterans trained for combat.
Civilian weapons are capable of rapid fire, and deadly at longer ranges.
We live much closer to one another, today..
Most folks couldn't survive for more that a week, without McDonalds or Safeway.
Most folks would panic, or not know how to care for themselves under stress, illness or danger.
Foreign enemies of the U.S. could certainly introduce WMD to their "allies" in the U.S. or "deliver" them themselves -- while the U.S. is too "absorbed" to respond.
Disease, hunger, heart-attacks, grudge killings, looting, etc, etc, etc, will lead to many deaths not directly related to fighting between adversaries.

The 9 million number is on the light side -- in my opinion.
It represents only 3% of our current population.....

As a nasty aside -- based on recent election results - there are a lot more than 3% of our voting population that "needs killin"....
