Americas biggest enemy is Democrats.
Pure and simple.
Thankfully most of them will be
killed in a full
out nuclear war.
They like to nest together
in large cities.
You have an interesting point there, they do in fact nest together in very large cities. And if these A-holes get a nuke war going, they will be among the first turned into ashes.
Another point to be made is if they start a civil war, just stop all deliveries to their big cities, shut off their electricity and that in turn will shut off their water and sewer systems. Their emergency generators for public works, also for cell towers, will run out of diesel. More would die of murdering each other than disease or starvation.
