Either way the decisions made today can impact on the lives of many Israelis. One cannot give advice without knowing what is like to wage a war. In terms of women I think that the mothers and wives of the soldiers have the roughest job of all. Staying in a sealed room hearing missiles overhead is no fun. Since the laws of Shemitta and Yovel have lapsed I don't see that any Jew automatically has a particular parcel of land in Israel.
Any land sold over the centuries no longer returns to the original owner.
There is a concept that every Jew has four amot in Israel. This is a fictitious four amot for halakhic purposes. It does not refer to a specific piece of land. According to many opinions the ten tribes will not return in the days of the Messiah. It certainly is not defined by citizenship.
