Filled with so much information and opinion about the politics of the Holy Land on my return, I decided I needed to to read something authoritative. And unbiased.
Finding books on the history of Israel, Palestine, the whole Middle East situation which are reviewed as fair and unbiased to all sides in the conflict is not easy, but one which seemed to stand out and which I have started reading is Stewart Ross's 'The Israel-Palestinian Conflict' published by Teach Yourself, 2010 edition, £9.99. It has helpful summaries at the beginning and is written in a straightforward and easy style.
If anyone else has read something helpful on this topic please share it with me.
