One of the little codes I live by is this: if you want the right answers, go to the experts. Since the experts know more than I will ever know this seems to be a sensible policy.
One such expert is undoubtedly Mr Israel Shamir
Mr Shamir takes a look at identity politics with regard to the current presidential race and offers some thoughtful ideas to help us navigate through the mess. This writer is more skeptical of Mr Trump than Shamir is but on the question of how "the narrative" is formed and promulgated he is unquestionably the expert.
If one has never read Shamir before I will mention that his criticisms of his own people, though often harsh, are said with that natural affection one has for one's own kind. He is never hateful, but he is very much a realist. He understands his own people and that is why his insights are so valuable.
