"I was referring to the end section of the AI Politics file; there are a slew of lines which toggle on or the AI's ability to accept various treaties and proposals. "
But there, doesn't exist a line to accept/reject treaty proposals...
I don't think that lines like reject to leave a system, or reject to give a gift, or reject to remove ships from a system, could determine that the AI never will accept a peace treaty.
"Has anyone **ever** seen an AI make peace?"
Sure. I saw it several times, in my test AI games. But only peaceful races, and no, I have not any example now!
