It’s the simplest conflict on the face of the planet. There is nothing complicated about it, just like the Holocaust was not a complicated thing to grasp. The problem is that no one is immune to propaganda. It’s why even mentioning China in the US makes people uneasy and abruptly stupid. Someone that might otherwise be one of the most articulate people you know, will suddenly become a 2-dimensional dipshit if you mention China, Israel, or Palestine. Undoing that indoctrination takes work—the kind of work a lot of folks are too lazy or busy to care about.
