Apologies for the long quote, but it's relevant. Written in 1891 by a Russian Zionist who foresaw the problems if the arab population weren't treated well by the incomers. He was largely ignored.
“We must surely learn, from both our past and present history, how careful we must be not to provoke the anger of the native people by doing them wrong, how we should be cautious in our dealings with a foreign people among whom we returned to live, to handle these people with love and respect and, needless to say, with justice and good judgment. And what do our brothers do? Exactly the opposite! They were slaves in their Diasporas, and suddenly they find themselves with unlimited freedom, wild freedom that only a country like Turkey [the Ottoman Empire] can offer. This sudden change has planted despotic tendencies in their hearts, as always happens to former slaves [‘eved ki yimlokh — when a slave becomes king — Proverbs 30:22]. They deal with the Arabs with hostility and cruelty, trespass unjustly, beat them shamefully for no sufficient reason, and even boast about their actions. There is no one to stop the flood and put an end to this despicable and dangerous tendency.”
“We who live abroad are accustomed to believing that the Arabs are all wild desert people who, like donkeys, neither see nor understand what is happening around them. But this is a grave mistake….The Arabs, especially the urban elite, see and understand what we are doing and what we wish to do on the land, but they keep quiet and pretend not to notice anything. For now, they do not consider our actions as presenting a future danger to them. … But, if the time comes that our people’s life in Eretz Yisrael will develop to a point where we are taking their place, either slightly or significantly, the natives are not going to just step aside so easily.”- Ahad Ha’am, Russian Jewish Zionist, 1891
