Even the classic movies, and some not so classic, explore themes which are bound by truths eternal. If so, I would suggest that foundation the basis of all nations, and perhaps families and individuals as well. We are shaped by the stories that we remember and tell and re-tell. Most of us have selective memories. And note what Mr. Wallace does not emphasize in his quotation.
Every political campaign is propagandistic by definition.
Any time there are two or more factions completing for the hearts and minds of a nation or the world, propaganda is by definition employed. The fact that something is propagandistic does not speak to the truth or falsehood of a proposition. Its focus is on a style of delivery. The debate is not that of 1947 as to whether Israel should exist. It is not whether Jews should de-possess Arabs in Palestine.
