Decolonization is a bloody and violent process. Once you colonize a place and the people that live there, the only ways that it will end is the near-complete extermination of the colonized peoples by the colonizers, or decolonization. There can never be a lasting, peaceful status quo, as the interests of the colonized and the colonizers are inexorably opposed. The colonizer wants more of what is and was the colonized's. The colonized want to keep their homes, and to not be subject to the colonizers. Both will use violence to achieve their ends.

The question of "how can peace be achieved in Palestine" is not "how can the current conflict be resolved," but instead "should Palestinians be subject to ethnic cleansing, including violently and directly as occurred during the Nakba, or should Palestinians govern Palestine?"
