Nobody is defending the settlers. Nobody.
The settlers are a great injustice. That being said, part of the truth is acknowledging that Israel removed their settlers from Gaza and the situation became worse. There is, unfortunately, no reason to believe that any other concessions will make a difference either.
The incident you mentioned is in the West Bank of all places. It is almost like arguing for Pakistan due to an incident in Bangladesh.
Israel may well have toppled Bibi and his far-right policies but Hamas had different plans.
>Israeli settlers in Palestine used petrol to set fire to Palestinian homes in the village of Duma on Friday, burning to death 18-month Ali Dawabsheh and critically wounding and maiming four members of his family.
