The young Palestinians are exposed to this radicalising material not only on social media. When they interact with the official institutions of their society, far from hate being challenged, it is reinforced. At school, terrorists are treated as heroes. In the media they are told the attacks are glorious feats. Just this week, official Palestinian TV described the Jaffa attacker as a martyr carrying out a complex operation. PA salaries are paid to convicted terrorists. Palestinian President Abbas never condemns the attacks or suggests that perhaps his people should stop trying to kill Israelis. Instead he echoes the prevailing narrative. Just last week he was reported to have sent a condolence letter to a recent attacker’s family. And the really bad news is that it’s likely that UK aid money supports all this reprehensible activity.
