"When a third party comes in and says “hey people, these are your new borders, drawn in our infinite wisdom,” it never ends well." - The two most recent examples are Kosovo and South Sudan. Third parties came in (the USA, mostly, in both cases, but also Europe). Are you against democratic self-determination? It is people's freewill choice whether to be unpeaceable. Extremist Palestinians choosing to be unpeaceable is their own fault and freewill choice and they should bear the natural consequences of their intolerance of non-Muslims.
