I don't have the novel in front of me, but Tito and his brother are discussing the old man. Tito's brother talks about a civil war being waged in America, a cold one.
Like the Cold War itself this civil war is waged below the surface, in spook country, over"”presumably"”the idea that terrorism & wartime does not mean the end of accountability & democracy.
It appears that it's between the people who were actually in the Cold War (the grown-ups), and their allies, and the current monumentally screwed up American intelligence community.
The lesson the grown-ups take away from wartime is that to lose liberty, is to lose the war (see also our timeline's Israelis). The lesson the people in charge take away from wartime is that it's a great way to impose control.
So where does it go?
