Have you seen how the IDF treat Palestinians on a day to day basis? I won't start posting videos but cursory research will show them exhibiting degrading and violent treatment on a daily basis. They are also prone to murder by sniper (including 22 journalists).That's not the army it's being instructed to do so by the current government.
This is anecdotal of course but I met members of post IDF trained Israeli travellers at a party in South America year ago. They were singing songs and telling jokes about killing Palestinians. They will be indoctrinated into hating them as part of the training. It follows as it makes it much easier to oppress and kill someone when you are brainwashed to see them as a lesser being.
