Out in the real world - how much "our countries take action" stuff actually happens when regular & systematic violence is occurring somewhere? When it does happen, how often does well-intended foreign intervention actually "fix" things - vs. turning into a yet another "park our troops there 'till we finally run out of patience" occupation? My read is that the many powerful factions which favor (overtly or not) the ongoing violent mess in/around Israel have (generally) very good understandings of the situation and its dynamics. And the benefits & costs - for them - of encouraging it to continue indefinitely. Vs. the opposing side is dominated by sincere but all-too-simple "make horrible things stop happening!!!" emotions. :(
