Open Zion on "subtext" of prisoner release: "Your lives—down to and including your very bodies—are under our control."

Here's the paragraph containing that sentence:

When Israel releases Palestinian prisoners, the subtext is entirely of a piece with the subtext of the whole occupation infrastructure: We control your lives. We decide who may go where, and when. We build walls, we issue permits, we arrest, we release. Your lives—down to and including your very bodies—are under our control.

The use of the word "subtext" here means that the author was taught to think like this in college.
