One of the issues surrounding the topic of Israeli settlements is the persistent impression that there was a stable, strong community of Palestinian Arabs that awaited Jews who were fleeing the Holocaust.
Actually, there have been Jewish communities there from the time of the Roman conquest, and Jews have been immigrating to Israel for centuries.
Likewise, there has been no solid, thriving Palestinian Arab community--just waiting to be displaced by Zionist Jews--In a post a few days ago, Zionists Kicked Palestinian Arabs Out Of Palestine? Why Do You Think Arabs Came In The First Place?, I wrote about how the Arab Palestinian population is not a permanent fixture in Israel--rather in 1948 many of the Arabs were recent immigrants who came to then-Palestine to take advantage of the improvements made by Jewish immigrants.
Another accusation made against the Israeli settlements is an offshoot of the previous idea that Palestinian Arabs in fact have strong ties to the land--strong, in fact, than Jews--by virtue of the fact that they are descendants of the Biblical Philistines and Canaanites, and at the very least their roots go back to the Arab invaders of then-Palestine in the 7th century.
