Once populations have established they are not going to erase each other from a territory they have to accept each other’s presence and have to treat those facts in a moral manner unless they “genocide each other” and morally this is not acceptable historically as much as the British deporting the Acadians in North America could not be an experience to be repeated without great historical damages to the British constitutional legacy. It would have been definitely a poor reflection of the Age of Enlightenment where Edmund Burke was very proeminent in influencing the British constitutional architecture in the colonies where respect of organic development was the principle.
Moreover Muslim when they assume fully that Islam reflects the same organic constitutional development that Edmund Burke acknowledged constitutionally definitely for Canada both Israelis and Arabs will have a better picture of British constitutional thinking.
This is why in Canada both the First Nations the different newcomers have their rights protected in Canada and cannot be deprived of their rights. In Britain, the Scots could see parliamentary devolution along the same lines of organic development.
