But why are we surprised by this? This has been going on since before Israel when terrorist groups like the Haganah and the Levi would terrorize Palestinians to force them to flee. Of course this policy continues because the leaders of these groups later became prime ministers, presidents, and generals.
Israel is a presently criminal state (settler colonialism is a crime) with a criminal and bloody history. We aren’t ostracizing it — we are pointing out the facts and demanding justice.
