Who will protect Palestinians from growing settler extremism?

Haaretz
For Palestinians in the West Bank, the sense of helplessness and frustration must be enormous. When they are attacked, they can almost never hope for justice within the framework of the legal system. Nor are they allowed to defend themselves. Nor can they expect the IDF to protect them. And even when they protest these injustices using nonviolent methods - marching, chanting and waving flags - they are punished with arrests and violence, with dehumanizing skunk gas and beatings. So what happens when there is no legal recourse or justice for the injured and no real civic structure, and when the moderates are systematically crushed? Surely these are the ideal psychological circumstances that make people vulnerable to the beckoning finger of extremism.
