For former Israeli soldier Nachshon Amir, defending the nation he grew up in was all he knew. Mr Amir spent several years beyond his mandatory service period in the Israel Defence Forces in the 1980s and 1990s. Nachshon Amir addressed an anti-Zionist rally outside the Melbourne royal commission hearings. His experiences cut to the core of tension surrounding a royal commission into anti-Semitism and hate speech in which both Zionist and pro-Palestine Jews have said they are targeted. Liberal MP Julian Leeser wants an audit of university courses that teach about Israel and Palestine.
