Israel can return land and lose an obvious trigger for war against it. Without any reasonable reason for going to war, would the Arabs really want to st art another major conflict in the area. Maybe they would - but the chances are far reduced. In my opinion it is a risk well worth taking, not only because the obvious reason for going to war is eradicated but because it is better for Israel's democratic credentials, its demographic requirements and its need to rebuild international support. Whatever Israel does it will always be in a greater or lesser position of risk in the region. It should do what it can to ensure it is at the lesser end of the pendulum. Does the occupation of land help it to defend itself. If the Arabs really wanted to rise up en masse against it, absolutely not. Can Israel cope with cross-border attacks and skirmishes from one or other hostile party. If it can't it might as well pack up now and call it a day.
