Jews are comfortably the majority in the State of Israel. Even assuming the current population growth of Arabs - around 3% - and 0% growth of Jews - in reality 1.5% - then it will take over 100 years for Arabs to become a majority. So much for the "fear" of a non-democratic Jewish Israel. As for comparisons with South Africa, you hit the nail on the head. The blacks were the majority there and in Israel Jews are the majority. There is two ways to solve the less priviledged position of arabs - one is to get some leaders who will look after the needs of the community - like Shas did for the religious Sephardi, preferably without the embezzlement - and the other is for some measures to bring Arabs into Israel society, like making national service compulsory.
