The State of Israel and the Politics of the State

Israeli politics has moved steadily to the right in recent decades. What is it about being an ethno state that just over time pushes the state in that direction? Is it something about universal military service and having people participate in this brutal occupation that then grinds their politics to the right as they reenter civil society? I'm curious if you think this was inevitable or if there were hinge points where things could have gone differentlyor if this was just the destiny of the state.
