There is a novel that I can almost remember, from the late fifties or sixties, about conflict and ultimately war between various communities and states on America's west coast after a nuclear war or global disaster of some sort. There were still cities left standing, so the collapse may not have been nuclear.
Actually, it may have been a civil war instead of a war between autonomous governments. Tribes of some sort had formed during the chaos and were fighting the larger government or governments. I think the tribes were depicted as better and more honest than the governments.
I remember reading it in a magazine, so it was probably not a full length novel. I'm fairly sure it wasn't a short story. It may have been a short novel or novella instead.
Telepaths were involved in the war in some manner. At some point, aliens also came into the plot. They were somehow secretly manipulating events behind the scenes, creating a number of the problems that had led to the war.
The story had an almost Pournelle feel to it, but I doubt he wrote it. There was a bit of a survivalist tone as well, and perhaps something of a libertarian feeling, with big government being portrayed as bad, and a belief conveyed that laws infringed on freedom.
Regardless of the political frame behind the story, I remember thinking that there were too many ideas and events stuffed into the story, making it feel like a sketch whatever its length was.
Of course, I read the story a long time ago and various details may have mutated over time. If I remember anything more, I'll update the question.
