True. What leads up to that is a far more interesting read. Matthew Bracken ('Travis McGee' on FR) wrote Enemies Foreign & Domestic. You should check it out. A very good read.
BTW, he sort of covered the scenario you outlined in his subsequent novels, Domestic Enemies: The Reconquista and Foreign Enemies & Traitors.
I actually have read his first book and was part of the way through his second but stopped mid way through as I just got too despondent with the thought. I have them all on the wife’s kindle. Maybe I should re-join that series. I honestly did think of his books when I posted my comment.
