It would be a rather absurd plan to cleanse a territory in which you are not only a minority, but also surrounded by Arab countries which were pretty adamant about refusing to accept the jewish state.

In practice, what had happened is that the jews accepted the partition plan. The reason the arabs didn't accept it, is because they simply wanted it all to themselves, not because they feared ethnic cleansing.

Using the term "settler" or "Colonializm" to characterize jewish immigration to Israel is racist and antisemite. As I mentioned, Arabs immigrated en-masse to the land of Israel throughout the 18th and 19th centuries, yet you refer to them as natives.
