There is not much you can do to change demographics but there are ways to cheat. First thing that must be agrees on is that if a palestinian state is one day created we will do land swaps and we will trade the arab triangle. Have the majority of Israel's arab population become citizens of the palestinians state then we can take their Israeli citizenship and just with the stroke of the pen we will have got rid of most the arabs. The haredi there is nothing you can do about but at least they are Jewish and also the majority of haredi live very ordinary lives it only a minority who are radical but which newspaper is interested in writing stories about ordinary haredi? We at the same time can make a push to encourage alliyah especially from western countries who will probably find integration than people from the third world or people who come as part of government operations to bring over big groups from countries like Ethiopia & Russia and usually even if they are not millionaires have at least some funds of their own which makes things easier for everybody. So solution is get rid of arabs and encourage alliyah minimise demographic damages.
