Because those are the types actions of people who use hate as a tool (same as Kissinger did). You can ask the same about Trump and why he hasn’t been assassinated yet (I know, apples and oranges). But what I’m trying to say is that people who are against such attrocities usually don’t prefer violence as a means to any end. Just my opinion on the matter.
The 1000+ Palestinian kids being killed daily by Israeli forces are victims of this “beef” stretching back thousands of years, which is messed up and unfair (stating it mildly). I think that’s what most people are pointing out, that and Israel bombing hospitals.
