Cohesion isn’t necessary; merely sympathetic movement.

They don’t have to become too cohesive to do real damage; think of “death by a thousand paper cuts”. Or a million rifle rounds. There have been successful insurrections that were simply dispersed aggregates of uncoordinated small groups bringing enough terror and discord to bring the existing system down. Of course, they weren’t able to build a new system, since they couldn’t agree among themselves on how to do it; we see instances of that in the world even now.

Twenty years ago, I would have happily handed tinfoil to anyone who seriously suggested that the US might become a failed state, or parts of it become a collection of failed states, especially in my lifetime. Now, I wonder if the odds haven’t “improved” enough for the gambling palaces of Macau or Singapore to make book on the proposition.

That depresses me. That scares me. But, mostly, it enrages me.
