Spooks, William Gibson

Today I am reading William Gibson's Spook Country. I'm on page 45. There's a powerful and frightening idea on this page.

Aljandro looked over his knees. "Carlito said there is war in America."
"A war?"
"A civil war."
"There is no war in America."
"When grandfather helped found the DGI, in Havana, were the Americans at war with the Russians?"
"That was the 'cold war'."
Alejandro nodded, his hands coming up to grip his knees. "A cold civil war."

I am full of anticipation and a little fear to see this idea develop on the page.
