I call false flag. Jews don’t call people monkeys, and the Israelis in Judea and Samaria have nothing against the monks in Latrun as far as I know.
On the other hand, Islam repeatedly calls Jews pigs and monkeys, so it makes sense that an agent provacateur would have painted this graffiti to inflame relations between Jews and Christians.
Shin Bet has been trying to make out that the Settlers are the enemy for quite some time. I irks me no end.
