In my own 1980s Hebrew school education, this stuff was entirely omitted. Begin was a good guy, a leader of Israel, the country where we were vicariously planting trees, a land without a people for a people without a land. You are fortunate to have been educated when you were, before history and a holocaust in amber froze Jewish education into a fairy tale vulnerable to the sharpest disillusionments when younger Jews learn a bit of what was omitted.
