What is the thesis in lemon tree by sandy tolan?

The thesis in "Lemon Tree" by Sandy Tolan is that the Israeli-Palestinian conflict is not simply a matter of two opposing nationalisms, but rather a complex web of individual stories and experiences that are often obscured by the larger political narrative. Tolan argues that by listening to the stories of ordinary people on both sides of the conflict, we can gain a deeper understanding of the underlying causes of violence and hatred, and work towards finding a more just and peaceful solution.
