Native Americans committed acts of violence against the European colonialists, but that doesn't make them "at fault". The ones who were at fault in that situation were the European colonialists who were dispossessing the indigenous people of everything they ever had. It is no different with the Israeli leadership and Zionist leadership, and the Palestinians (Israel being the European colonialists who are dispossessing the indigenous people, and the Palestinians being the ones who are being dispossessed). When people commit acts of violence as a form of resistance against being dispossessed, that doesn't make them at fault. It's perfectly legitimate to resist being dispossessed. The ones at fault are the ones who are dispossessing the indigenous people of everything they ever had.
