Time runs in a circle, and that's the value to learn from history. You have to learn how the border ends up here today from a long time ago in order to understand what the real issue is and where the root causes lie. The author did broad research and threads the extended timeline elegantly. Warning: the reality is always much more brutal than the cable news, and it takes some nerve to read on, but it is also impossible to put it down. Facing reality could be some torture, but it still beats accepting alternative facts, 100 of 100.
