1. It is irrelevant how many jewish people were in the UK. Historically they did not want them. There is plenty of evidence for this from early times.
2. Shlomo sands is an academic at Tel Aviv university.
3. The holy bible is not revered by all people on planet earth. Any geographical references indeed relate to where jews were but the idea they lived in a state called Israel which contained only people who were jewish, and that it extended as far as Jerusalem are myths. We must remember judaism is a religion not a race of people and that people over centuries change their religion at will. Many people in that region adopted judaeism first, then became christians and then later Moslems over time as culture is not immutable.
4. The Canaanites never left the area unlike the jews who moved on naturally to other areas of the world. There were for example large populations in Mesopotamia and other areas. They were never cast out of Palestine. That is also just a myth with no archaeological evidence to show it happened. The romans never cast out populations they overcame because therwise who would they tax?
5. My facts are well researched and not false. The Zionist state from its earliest days with prime minister David Grunn taught the book of jacob in the bible as historical reality rather than myth that you say you accept, but this means the majority of the population of Zionists grew up being told the book of jacob was historical truth. They needed to do this to perpetuate their false claim over the land and although like many of the early leadership such as David Grunn were aethiests they saw the value of this religious myth.
Its the same reason most of them were encouraged to change their names to Hebrew -up to that point a dead language like latin- sounding names in order to make them appear historically connected to the bible stories. David Grunn as you probably know became David Ben Gurion. Golda Meirs real name was Goldie Mabovitch, Menachem Bagin was Menakhem Volfovich and even the present prime ministers father was called Benzion Mileikowsky.
