"Truth" is an enigma in the eye of the beholder. If a young child is taught that a square is round & you ask the child to tell the truth & the child replies a square is round, is he or she not telling the truth?
Facts however are documented. Let us consider the facts regarding the truth as to the Palestinians.
The Truth about the Palestinian People
Facts are not necessarily "well documented" particularly with something as subjective as history. As they say - history is written by the victor, and it's the winner that controls the narrative. One good example is how the conflicts between indiginous Americans and American settlers were portrayed and how that narrative has changed. Or, how about the "happy slave" narrative?
Facts work in mathamatics. In history, where fiction and fact meld depending on who is narrating and interpreting? Not so much.
