Explanation: There are many areas of land that are within the boarders of the state now known as Israel, that are under Palestine control. These places are Gaza and the West Bank. However, it is important to note that there is alot of Israeli settlement and jewish settlement in the west bank. Not only that, but much of the agricultural land is owned by the state of Israel. Originally, the purpose of this settlement was to reclaim the land that was promised to the jewish/Israeli people in the zionist ideology. The zionist ideology is that the land that was once known as Palestine before 1948, shall be reclaimed by the jewish people by any means nessacary. They attacked Palestine and took their land, and now there is little land left for the Palestinians.
