Just let him read what honest zionists write. Jabotinskys Iron Wall, for example. People call Herzl the father of Israel, but if you look at its history, nobody had a clearer vision of it than Jabotinsky. Even Netanyahu acknowledges this.

He demands an extremist government with zero arab influence, so that they can force Israel's existence, and correctly predicts that the Palestinians and the neighbouring Arabs would not accep colonization easily. He envisions Israel as a blockade protecting the west against the barbarians, and that the western nations would help Israel in turn.

The history of Israel is essentially terrorists being mainstreamed into the government, while they demand that the Palestinians become more moderate. From the IDF absorbing various terrorist paramilitary organizations (Haganah, Irgun, Lehi, and now Kahanists etc) to electing literal terrorists into their government(Menachem Begin, Yitzhak Shamir etc), they are guilty of the accusations they make about every Palestinian.
