Writes a friend:

Lew, what goes through my head when reading this is the reality that one day in the not-too-distant future, the US government will employ such tactics right here, over the United States – in the same way they have handed us a color revolution: perfected overseas, to be used against the citizens.

World War One: the Europeans perfected their weaponry against the colonies in the preceding decades, then brought it home to fight each other.  We will relive this. See this.
