yeah but how far back are we going to look?
what if the mongols demanded back turkey etc?
however the most fraudulent landgrab in european history must have been kosovo given to the albanians.
thats poitics, all nation borders are drawn with blood.
Almost every powerful nation has had a stronghold on the territory of Israel, British, French, Turks, Arabs, Romans, Greeks, Persians, Assyrians, Babylonians etc, .. the first to rule this region was the Canaanites then Conquered by a certain Hebrew tribe that ended up being known as the Jews, who established the nation of Israel and wiped out most tribes living in the land except for The Philistine, who are now known as the Palestinians.
Most Canaanite tribes were Hamitic tribes except for the Philistines who were both Hamitic and Semitic and of course since The Israeli's were a Semitic tribe it was always easy for the Philistines to recruit Hamitic tribes as allies to fight with Israel, hence the term Semitic and antisemitism, however the Philistines could never take over the land during Israel's 500 year reign, then came the Babylonian exile in 550 BC, followed by Greek rule and Roman rule until the second revolt in Jerusalem which caused the name to change to Palestine as stated by BigCyp.
Anyway make a long story short I would suspect that the Israeli's have as much right to claim that land as anyone since they held a 500 year reign
