Funny people bring up Native Americans, the Aborgines of Australia got it bad, the Iniuts for Canada got the staft, Tibet still gets the shaft and the Native people of every South, Central American country got the biggest shaft and the Kurds are currently getting butt-slammed by the Iraqi, Iranians, Turks and Syrians collectively!
There is no question but that the Native Americans suffered both indignities and atrocities at the hands of European settlers, the American colonies and later at the hands of the US government, but this is entirely unrelated to the conflict between the Arabs and Jews. While the early Europeans either defrauded the Native Americans, who didn't well understand the concept of private property, out of their land or took it by force, during the Ottoman period and the Mandate period, the Jews bought the land from Arabs who well understood the concept of private property, and the British reports to the League of Nations, available on the UN website, show that British courts found the Arab claims of land theft by Jews were without merit.
During the 1948-1949 war, no more than a few thousand Arabs were forced from their land and these instances occurred in places each side was trying to drive the other side out. After the war, with only a few exceptions, the Arabs who had left did not petition the Israeli government or courts to return or an individual basis or to reclaim property, instead they waited for the Arab countries to destroy Israel before claiming their property. Regardless of whether that property were in Haifa or Tel Aviv or Philadelphia or Chicago or Los Angeles or San Franciso or London or Paris or Madrid or Cairo or Damascus or Amman or Tehran that would constitute abandonment of property.
