“...what would go down, over time, would make our Civil War look like a walk in the park on a warm spring day.”
Trust me.
Considering the dead from the civil war as a percentage of the population, such a conflict today would result in several million dead, I think the figure I read was 4 million.
Remember too, that there would no doubt be foreign players,
Russia, China etc that would want to influence the out come.
Not a pretty picture to contemplate.
The way I recall it was that in our Civil War killed 600,000 out of a population of 30 million.
Scaling to today's population of 300 million would result in 6 million dead.
