> Not true. Jews purchased many of the lands during British and Ottoman rule. When Israel was formed the Palestinians were given the majority of the territories.
"The Jewish State allocated to the Jews, who constituted a third of the population and owned about 7% of the land, was to receive 56% of Mandatory Palestine, a slightly larger area to accommodate the increasing numbers of Jews who would immigrate there." (https://en.wikipedia.org/wiki/United_Nations_Partition_Plan_...)
Notice that the areas allocated are not continuous most of the area is a desert (the entire southern region). It also doesn't mention who owned the rest of the land so the 7% number isn't valuable.
