“blowing themselves up.”
That’s much like blowing oneself up when the insurgency reaches the bottom of the downward slope and there is only 1 event of the greatest magnitude.
On the other hand, civil war is a square wave. It has close and far, and deep and shollow, but the magnitude is only like a magnum 4 earthquake.
Not so with an insurgency. When it reaches its point of singularity (the bottom of its downward slope)… BANG!
I don’t think the US, because it is a Republic, has ever had an insurgency. China had one in Chairman Mao, and 60 million people died. The closest the US came to having an insurgency was when Nixon was POTUS.
But then the insurgency kinda fizzled out, when they started calling themselves Baby Boomers and the leaders Republicans 🙂
